Background:

The quality of the assessment instruments is essential in the learning assessment process.

Objective:

To determine the difficulty and discernment indexes of the Human Ontogeny and SOMA ordinary final test subject.

Methodology:

A cross-sectional retrospective study was conducted on the Ontogeny and SOMA subject, from 2017 to 2018 academic year at the Sancti Spíritus Faculty of Medical Sciences, 163 final ordinary tests were processed, 30 % of the examinees selected by stratified random cluster sampling, the difficulty and discernment index were calculated by questions, topics and sciences.

Results:

The number of expected and real items, according to the class hours for each science, was adjusted, but not in the subjects (Ontogeny of 17 expected items were dedicated 12 (70.5 %), in SOMA of 34 expected items 29 were dedicated (85.2 %), the difficulty index by subjects, sciences and syllabus was moderately easy (0.74-0.86) as for the exam as a whole. The discernment index of the topic Ontogeny was higher in the syllabus 1 (T1: 0.37 vs. T2: 0.24) and similar in SOMA (T1: 0.40 vs. T2: 0.39) and [Embryology (T1: 0.39 vs. T2: 0.31), Anatomy (T1: 0.39 vs. T2: 0.37)]. At the science level questions, the lowest discernment index was found in question 1 from the first syllabus (0.22), the rest had discernment indexes higher than 0.30.

Conclusions:

Both topics have a similar discernment index. The difficulty index was moderately easy.
