German faculties of medicine can award 60 percent of the university places available after pre-allocated places have been deducted through a university selection procedure (AdH) with the addition of the places as yet unfilled from the quota reserved for the best Abitur results. The selection procedure should be primarily performance-based [http://www.landesrecht.sachsen-anhalt.de/jportal/?quelle=jlink&query=HSchulZulG+ST&psml=bssahprod.psml&max=true&aiz=true]. As well as the Abitur grade obtained (“level of qualification”), the individual grades given on the Abitur certificate and/or

The potential selection tools differ by the extent to which the Abitur grade continues to dominate as a performance criterion and in the logistics they require. None of the criteria has been validated prospectively in relation to professional success [1].

Up to the 2011/12 winter semester, the Abitur grade obtained was the sole selection criterion applied in the selection procedure used at the Magdeburg Medical Faculty. Because Abitur grades obtained in the individual German federal states are not directly comparable however [2], the faculty decided to introduce a test of knowledge from winter semester 2012/13 onwards for the selection of applicants¹. The natural sciences test used at the Medical Faculty Hamburg (HAM-Nat) is a multiple-choice test with questions on the aspects of biology, physics, chemistry and mathematics that are relevant to medicine, which was specifically developed and tested for the selection of medicine applicants [3], [4], [5], [6], [7]. The Hamburg Medical Faculty introduced the selection test primarily to reduce drop-outs from the 1st part of the course [3]. The HAM-Nat gives candidates with outstanding knowledge of natural sciences higher chances of admission. The aim is to increase and harmonise performance level in the first semesters, particularly in the area of natural sciences. It is also intended to increase the number of students from the largest student group (the 60% selected by the university selection procedure) who take the 1st part of the German Medical Examination at the proper time.

According to the regulations governing university capacity, 191 to 193 students annually begin to study medicine in Magdeburg, approx. 150 of whom are selected by the faculty itself through the university selection procedure taking waiting lists into account. Until 2011, selection was based on Abitur grade alone. In the new selection procedure, from 2012 onwards 700 applicants who put Magdeburg as their first choice, are identified in a pre-selection procedure and ranked by the average Abitur grade obtained in their university entrance qualification. Applicants in places 1-25 are admitted directly to the course i.e. without taking the test (quota of outstanding students). From place 26 onwards, university places are awarded on the basis of the average Abitur grade combined with the result of the selection test. For this purpose, the average Abitur grade is calculated as a linear score ranging between 60 (for an Abitur grade of 1.0) and 0 (from a grade 4.0 onwards). Up to 59 points are allocated to the result of the HAM-Nat test. From place 26 onwards, an applicant is ranked by the total of the two scores [http://www.med.uni-magdeburg.de/Studierende/Studieng%C3%A4nge/Humanmedizin/Bewerbung+und+Zulassung/Hochschulauswahlverfahren+Humanmedizin+%28hochschulstart_de%29-p-13682.html]. When students have the same overall score - as also occurred in earlier years - voluntary service (e.g. voluntary military service, federal voluntary service) recognised under University Admissions Foundation regulations [http://www.hochschulstart.de/fileadmin/downloads/Gesetze/g03.pdf] is taken into account. When students are ranked equally, a random selection procedure is applied.

In a first stage, this study compares the university’s selection procedure from 2011 to 2014 in relation to number of applicants, the Abitur grade obtained by applicants and those admitted, their gender distribution, place of origin, test results and the change in rankings made on the basis of the test. Finally, the students selected are characterised in relation to their application behaviour and their further study plans. As soon as results of the state examination M1 are available for further cohorts, a subsequent study will investigate how the aims of the faculty

promoting completion of the standard period of study are achieved with the introduction of the new selection procedure.

The selection procedures applied at the university in 2011 (without HAM-Nat) and in 2012-2014 (with HAM-Nat) are compared in relation to participant statistics and test results. The internal consistency [8] of the selection test (Cronbach’s α) was determined to assess reliability.

The HAM-Nat test is an economical procedure in terms of personnel and time and is therefore cost-effective. In Magdeburg, approx. 45 members of staff are simultaneously involved in administering the test in ten lecture rooms. Preparation for the test consists of setting the questions, the question review process and co-ordinating the questions at the three sites involved (Hamburg, Magdeburg, Berlin). The tests are a paper-based assessment analysed by a standardised procedure (IMS, KLAUS). The test statistic is available on the day of the test, which means that decisions can be taken about items which may be of questionable quality. Test participants receive the decision on their admission very quickly. All results and the assessment are replicable so that the test procedure provides legal certainty.

In the initial stage of a two-stage qualitative-quantitative methodological procedure, 17 female and 15 male university entrants who had taken part in the 2012 or 2013 university selection procedure were interviewed. The interview was analysed using the basic techniques of qualitative content analysis [9], [10].

On the basis of the results of these interviews and in line with the results of the student survey [11], [12], the university entrants of the 2013/14 winter semester were asked to complete a written questionnaire anonymously as part of the introductory event. The questionnaire contained 36 questions predominantly based on a 5-point Likert scale “1= does not apply at all” to 5= “fully applies” with free text fields. It is given in full in the appendix with response frequencies.

Overall 147 out of 191 university entrants (77%) from all admission quotas completed the standardised questionnaire. A response with scores 4 and 5 is considered below to express agreement with a statement. The data collected were analysed using SPSS Statistics version 21.

To demonstrate the influence of the HAM-Nat procedure on the composition of the students admitted, the selection procedures used in 2012-2014 were compared with those used in 2011. Up to and including 2011, applicants expressing all preferences for location were admitted in the order of their Abitur grades up to the cut-off ranking. In 2011, the cut-off grade was 1.5. In the HAM-Nat procedure, the 700 applicants with the best Abitur grades who had made Magdeburg their 1st preference were pre-selected. Admissions were awarded on the basis of Abitur grade and HAM-Nat result up to the cut-off ranking. Because not all the students admitted enrol in the first year but intake capacity has to be completely used up, the number of those admitted by the university selection procedure is greater than 60% of the fixed intake capacity.

From 2011 to 2014, the number of medicine applicants who had put Magdeburg as their 1st preference remained the same after a decrease related to the introduction of the HAM-Nat (see Table 1 [Tab. 1]). Because the number of applicants with Abitur grades in the 1.3-1.7 range, whose chances of admission are significantly changed by a good test result, has substantially increased, from 2013 onwards there was an improvement in the Abitur grade up to which applicants were invited to sit the HAM-Nat in Magdeburg (in 2012 students with Abitur grades to 2.9 were invited while from 2013 onwards students with Abitur grades to 2.0 were invited). The Abitur grade which would have been good enough for admission had selection been continued on the basis of Abitur grade only remained about the same from 2012 to 2014.

In 2012, only 58% of the applicants invited to sit the HAM-Nat actually sat the test; since 2013 the quota of participants has been approx. 80%. The average Abitur grade obtained by those admitted has become lower i.e. applicants with less good Abitur grades have been given a chance on the basis of their good test results (see Table 1 [Tab. 1]). Applicants with very good Abitur grades but little knowledge of natural science have lost their chance of admission. This is in line with the intention of the procedure to select applicants with outstanding knowledge in the natural sciences. In 2012 and 2013, the HAM-Nat result shows weak correlation with the Abitur grade (i.e. applicants with low Abitur grades have high test scores), but this is not the case in 2014, although the internal consistency of the test is almost the same in all three test years (Cronbach’s α 0.87 to 0.89).

The selection efficacy of the tests, measured by the Paternoster effect [13], increased, particularly between the first and second year of the test. The “Paternoster effect” quantifies the proportion of those admitted who were offered a place only when the HAM-Nat result was taken into account, out of all those admitted. In 2012 it was 56% (see Table 1 [Tab. 1] and Figure 1 [Fig. 1]) and subsequently increased to about two thirds (see Figure 2 [Fig. 2]). The increase can be explained by the improvement in cut-off Abitur grade at which applicants were invited to take the HAM-Nat test, which meant that the differences in the Abitur grades of the test participants had less effect on selection.

Figure 1 [Fig. 1] shows the Paternoster effect. Test participants with a direct ranking up to 150 (on the left of the vertical line) would have obtained a place before the introduction of the HAM-Nat. After taking the test result into account, participants with an overall ranking up to 150 (under the horizontal line), but a direct ranking above 150 (i.e. applicants in the lower right quadrant), are the “winners” from the new selection procedure, because they are admitted only when their good test results are taken into consideration. Participants in the lower left quadrant have retained in the test their pre-existing chance of admission based on Abitur grade. Despite the fact that their Abitur grade of 1.2-1.5 made them eligible for admission, applicants in the upper left quadrant were refused a place because of their test results. Applicants who did not sit the test were given, as statutorily required, overall rankings after test participants.

Male participants achieved about 4 points more than female ones in the HAM-Nat in all three years. This meant that the proportion of male students admitted increased compared with a procedure based on Abitur grade only.

For some of the university entrants achieving the best possible Abitur grade (54% agreement) or being well prepared for a future university course (38%) was already important when they chose their advanced courses at school, but the most important factor was generally interest in the content of the advanced course (93%).

One third of those interviewed felt that their school had prepared them well for the HAM-Nat. This value was above average in the case of students from science or technology specialist schools (52%) and of those who had recently passed the Abitur (43%). 86% of university entrants who have passed the selection test see preparing for the test as helpful for further studies as well.

Important reasons for taking up the study of medicine are, besides a dominant specific interest in the subject, the opportunity to help people, to work with people and to do something useful for the community that being a doctor provides (see Figure 3 [Fig. 3]). Although interest in the natural sciences was highly rated, later scientific activity plays a subordinate role only. 90 per cent of those interviewed are attracted by the variety of professional opportunities; personal inclinations and abilities are almost as important. 7 out of 10 future doctors were certain they wanted to enter this profession even before they had finished school.

In addition, analysis of the interviews demonstrated that, besides the variety of opportunities on the job market, the prospect of a high income was obviously critical for the decision to study medicine, although this was described as important by only 17 percent of university entrants completing the written questionnaire, an indication of socially desirable response behaviour in the written test.

46 out of 127 university entrants (36%) stated that they had at least one parent who worked in the health services. For 18 of them (39%) advice from parents, relations or friends was important in choosing a subject, while only 17% of the university entrants whose parents were not in the health services mentioned this. The father’s advice appeared to make more of an impression than the mother’s.

At the start of the course, all students are optimistic about succeeding (98% agreement). High practical relevance (96%), the acquisition of much factual knowledge and “hard work” (86%) are associated with the course. Although scientific activity plays only a subordinate role in the choice of subject, the university entrants expect scientific work (79%), discussion of theoretical questions (78%) or orientation towards research (69%) to form part of their studies. Analysis of the 11^th Student Survey [12] showed that the students of human medicine wanted primarily to work with people. For effectively every interviewee the most important aim was to succeed in their studies and then to find an area of work that they enjoyed (97%), to acquire lasting knowledge (95%) and to live up to their own standards (94%). 85 per cent of future doctors also consider a life outside their studies to be important.

The main reason for applying to the Medical Faculty in Magdeburg is the relatively good chance of being admitted to study medicine (see Figure 4 [Fig. 4]). Hence Magdeburg is considered a good choice because of the lower student numbers, good learning conditions and lack of tuition fees. For almost one applicant in two proximity to the home town is important.

Most university entrants said that they come from Saxony-Anhalt (N=42), North Rhine-Westphalia (N=20), Berlin (N=17), Bavaria (N=15) or Lower Saxony (N=12). While the university entrants from Saxony-Anhalt appreciate regional proximity and the social environment offered, the high chances of admission were more important for the remaining interviewees.

It had already become evident in the preliminary interviews that Magdeburg was often chosen for tactical reasons. The city was considered by the interviewees less as a place to live than as a place to study which provides the necessary conditions for graduating in medicine.

No problems were associated with introducing the HAM-Nat test as selection procedure at the Medical Faculty Magdeburg. Acceptance by participants is high: 86% of university entrants regard the HAM-Nat as helping them in their further studies. After the number of applicants naming Magdeburg as their first preference had decreased substantially and all applicants with an Abitur grade up to 2.9 had been invited to sit the test in 2012, the year the HAM-Nat was introduced, the number of applicants almost doubled in the subsequent year thus returning to the level of applications received in 2011. Evidently it took a year for applicant behaviour to adjust to the new selection procedure. In 2013 in comparison with 2012, despite the better average Abitur grade obtained by the HAM-Nat participants (the cut-off grade for an invitation to sit the test was now an Abitur grade of 2.0) the students admitted via the university selection procedure had a worse average Abitur grade (going from a mean grade of 1.55 to 1.68). The high Paternoster effect at two thirds clearly shows that a good test result leads to admission and that applicants with weaker Abitur grades also have a chance of admission. This was intended.

Male applicants obtain substantially better HAM-Nat results on average than female applicants, which means that more male applicants are now admitted than was the case earlier (see Table 1 [Tab. 1]). This phenomenon also occurs in Hamburg as well as with other aptitude tests e.g. in Graz [14], [15]. One reason could be that male applicants show greater interest in natural sciences which is already evident in the advanced courses chosen at school. Our 2013 Student Survey shows that male students are more likely than female students to have chosen mathematics (male: 45%/female: 31%), physics (10%/4%) or chemistry (15%/10%) as an advanced course at school. The latter tend to choose German (15%/39%), English (27%/33%) and biology (49%/50%). With this subject profile female school-leavers obtain better grades in the Abitur than males (e.g. in 2011 in North Rhine-Westphalia about 60% more women than men were awarded an Abitur grade of 1.0 to 1.9 [http://www.it.nrw.de/statistik/analysen/stat_studien/2012/band_75/wl_z089201254.html). As a result, the proportion of women in the applicant population is greater than that of men [16]. The emphasis of the HAM-Nat test is different from that of an admission procedure based on Abitur grades alone.

In the case of applicants from Saxony-Anhalt, the principle reasons for their choice of university, besides regional proximity and the social environment offered, are the good conditions for studying and the feel-good factor at the university. The faculty’s public relations in the region focussed on a positive presentation of the university; it should be maintained to ensure new new physicians for Saxony-Anhalt particularly for rural areas. For applicants from other federal states with an average Abitur grade >1.6 in particular, the relatively good chances of admission, if they have good prior knowledge of the natural sciences, are the most important factor. Thus preferences are used tactically by approx. 80% of medicine applicants to obtain the university place they want. Specifics relating to curricula and key profile and research areas are not critical for their application.

With the introduction of the HAM-Nat the number of Saxony-Anhalt applicants admitted to Magdeburg initially doubled (see Table 1 [Tab. 1]). It reduced again in subsequent years, which was predominantly caused by the increased proportion of applicants from other federal states. The HAM-Nat, as a performance-related selection procedure, is not suitable for giving preference to natives of Saxony-Anhalt in the application procedure if they do not perform better than other applicants. The law governing university medical education and the regulations of the University Admissions Foundation have not given and still do not give preferential treatment to local applicants in the university selection procedure http://www.landesrecht-hamburg.de/jportal/portal/page/bshaprod.psml?showdoccase=1&doc.id=jlr-VergabeVStiftVHArahmen&st=lr], [http://wcms.uzi.uni-halle.de/download.php?down=28395&elem=2554892] in accordance with the prohibition of discrimination in article 3 par. 3 of the Basic Law. If students admitted from outside Saxony-Anhalt return to their home states after university, medical care within the region may be put at risk more than previously by the lack of young doctors. Only 64 out of 138 university entrants surveyed (46%) can envisage setting up a local practice after university. Of these 23% are considering becoming a general practitioner. Only 9% would like to practice as a general practitioner in a rural region, which is the reason for concern about future healthcare in rural areas [see also [17]].

No conclusion can be drawn on the basis of this study on the effect of the HAM-Nat selection test with regard to the success achieved in their studies by those selected. In the future, further analyses will study the parameters of successful study, particularly the number of drop-outs and the results of the 1st part of the German Medical Examination (M1). The M1 State Examination tests basic knowledge in the natural sciences which is also the target of the HAM-Nat test. Since it is impossible to compare the results of the test with those of the 1st part of the Medical Examination obtained by our HAM-Nat partners in Hamburg and Berlin because of the pilot courses there, it is all the more interesting to continue to observe how successful the Magdeburg HAM-Nat cohorts are in their studies.
