Assessment methods

The final examination is designed to assess the achievement of the main learning outcomes of the course: (1) To know the aetiopathogenesis and macroscopic and microscopic morphological features of the main diseases affecting the organs and systems addressed in the course; (2) to know how to recognize an organ lesion and describe it using the appropriate terminology; (3) to be able to formulate and discuss a list of possible differential diagnoses starting from a macroscopic lesion and suggest how to establish a final diagnosis.

The examination consists of a written test, a practical test and an oral test. The three tests are taken at the same time, usually on the same day. Given the close integration of all three tests they cannot be taken separately.

a) Written test . The aim of the written test is to ascertain that the student has an adequate body of knowledge relating to the course contents. Students who fail the written test are not eligible to sit the subsequent parts of the examination. The written test includes 20 questions (10 multiple choice questions and 10 short open ended questions).

- Each multiple choice question has four alternatives and only one correct answer. The possible scores are 0 (incorrect) or 1 (correct). Failure to answer is deemed incorrect

- In open-ended questions the answer must fit in the space allotted. The score ranges from 0 to 1 depending on the accuracy of the answer and adherence to the question. Failure to answer is scored zero.

- The time allotted for the written test is 90 minutes. During the test students are not allowed to use support material like textbooks, notes or computers.

- A total score of at least 12 points is required to pass the test and sit the subsequent parts of the examination.

b) Practical test . The aim of the practical test is to ascertain that the student is able to recognize an organ lesion and knows how to describe it using the appropriate terminology. The student is shown a pathological organ or photograph reproducing an organ lesion. The student must recognize the organ and species to which it belongs, identify the lesion and describe it using the standard international descriptive method presented during the course. The candidate is deemed suitable if the test is passed. Students who fail the practical test are required to resit the entire examination.

c) Oral test

The aim of the oral test is to ascertain the student's ability to apply his/her body of knowledge with the necessary logico-deductive skills. The oral test is usually based on the lesion observed in the practical test. The student is asked to formulate a list of differential diagnoses fitting the lesion morphology and to discuss the elements for and against the various hypotheses advanced, suggesting how the final diagnosis could be reached. Test questions are designed to elicit in-depth information on the diseases called into play. Special attention is paid to the student's ability to undertake transverse reasoning and to link the course information with the information acquired from courses attended in previous years. The oral test score ranges from 0 (zero) to 10 (ten). A total score of at least 6 points is required to pass the test. Students who fail to obtain 6 points are required to resit the entire examination.

The final score expressed in marks out of thirty is sum of the oral test score and the written test score and shall be recorded immediately. Students awarded full marks in all parts of the examination shall be awarded the top mark of 30 cum laude.

Procedures concerning the booking and dates of the exam sessions

Students can only book their oral test following the instructions available on the Alma Esami online system: (https://almaesami.unibo.it/almaesami/welcome.htm ).

- Examination dates appear in special windows for course students and are scheduled throughout the year for out-of-course students.

- Course students are not entitled to sit examinations outside the specified dates.

- Examinations cannot be taken without fulfilling the propedeutic requirements specified by the degree course committee.

- If all candidates cannot be examined on the scheduled day, depending on the time available the examiner is entitled to shift the examination date of unexamined candidates drawing up an examination schedule on the first examination day.

- Students failing to pass the oral test are entitled to resit the entire examination.
