How is evaluation done?
First, the number of weighted and solved exercises is determined for each group of exercises. Wrong answers and non-processed exercises are not considered. In the next step, the number of correct answers is converted into a scale with the mean value 100 and a standard deviation of 10 ("standard value"). This also considers the difficulties of the exercises determined by empiric methods so that the results of different TM-BASE tests can be compared with each other (even if both the random samples of the participants and the test exercises were different).
If a test participant achieves a standard value of 100 his performance in the test corresponds to the arithmetic mean – always based on the total number of participants.
The standard values of approx. 34 percent of all test participants are between 100 and 110; the same number applies to the standard values between 90 and 100. Approx. 48 percent of the participants achieve values between 100 and 120; the same number applies to values between 80 and 100. Only approx. 2 percent of all test participants achieve values above 120 or below 80.
What is the purpose of this? Conversion into standard values enables direct comparison of the results from various groups of exercises or comparison with the results of the total test, even in case the individual groups of exercises include differing numbers of exercises.
The "percentage rank" states the percentage of participants that achieved a lower or identical result. With a percentage rank between 30 and 70 the test result is classified as being an average result. Here, "average" should not be interpreted in a colloquial manner – a "slightly weaker person" amongst a high number of top-performing persons is still good in absolute terms!
Contrary to the standard values, the differences between the percentage ranks do not allow for drawing any conclusions on the extent of the difference between the underlying scores.
Example: A percentage rank of 94.5 means that 5.5 percent (100 minus 94.5) of all test participants achieved a better result. Correspondingly, 94.5 percent achieved an identical or poorer result.
How can the results of the total test be interpreted?
The initially stated evaluation rule also applies to the total test. The standard value of the total test is denominated as "test value". Furthermore, a percentage rank is also stated for the test value.
Additionally, a "grade equivalent" is calculated for the test value. When converting the test value into a grade scale, the TM-BASE results and bachelor grades can be combined. Conversion is made so that the distribution of the grade equivalents of all test participants shows the same standard deviation like the bachelor grades. This allows for optimal weighting with the bachelor grades. The average value of the grade equivalent is approx. 2.5, so that approximately two thirds of the TM-BASE grade equivalents are between 2.0 and 3.0. The best possible grade equivalent is 1.0; the worst grade equivalent is 4.0. However, grade equivalents better than 1.5 are very rare.
The registration phase for the test dates in 2019 has started on 8 January. Early registration is recommended so that you will be able to take the test at your preferred location and time.
The registration phase for the test date on 29 June 2019 ends on 11 June!
Dates, deadlines and test locations are stated here.
As of the winter semester 2019/2020 the Frankfurt University of Applied Sciences is considerin the results of the TM-BASE for its Masters' Programme Accounting and Finance (M.Sc.).
Important: If you want to apply for this programme you need to take the TM-BASE in English.
The prognostic power of TM-BASE has been proven in a scientific study with 247 master’s graduates. The test result predicts the final grade very well: The correlation between the test result and the final grade is r = .44.
