EDiR: Scoring of the examination. FAQs

 

How do I pass the EDiR examination?

 

The scoring of the EDiR examination has two components:

  1. Weighted written score (WWS). It is calculated as follows: 
    70xMultiple_Response_Questions + 30%xShort_Cases
  2. Clinically Oriented Reasoning Evaluation (CORE)

 

In order to pass the EDiR examination, your score in each component has to be equal or higher than the pass-mark of each component.

 

What is the pass-mark for each component?

 

The pass-mark for each component is calculated using the following formula:

Pass mark = Mean score – 1 x Standard deviation

 

Even though the pass-mark is different from one exam to another, it remains quite stable:

Pass mark(WWS) = 53% approx.

Pass mark(CORE) = 58% approx.

 

This pass-mark is calculated taking into account all candidates taking the exam simultaneously the same day.

However, a fixed minimum and maximum pass-marks are defined:

Pass mark(WWS) = Minimum(50%) and Maximum(60%)

Pass mark(CORE) = Minimum(55%) and Maximum(70%)

If the pass-mark calculated for a specific exam is below the minimum, the minimum pass-mark will be used. This will ensure that all candidates passing the exam have the required competences.

If the calculated pass-mark is above the maximum, the maximum pass-mark will be used. This will ensure that all candidates having the required competences, will pass the exam.

 

How are the multiple response questions scored?

 

Each multiple response question has a maximum score of 1 point. There is no negative marking in any of the components of the exam. The multiple response questions are calculated using this formula:

  • n.Correct = number of answers that the candidate has selected as correct and are actually correct
  • t.Correct = total number of correct answers
  • n.Incorrect = number of answers that the candidate has selected as correct but they are actually wrong
  • t.Incorrect = total number of wrong answers

Example. We have the following question:

Regarding small bowel lipoma: Which of the following statements are correct?

  1. Imaging features at CT are equivocal in > 50% – WRONG
  2. They are more common than lymphangiomas – CORRECT
  3. They are most common in the jejunum – WRONG
  4. Lipomas larger than 2 cm are suspicious of malignant degeneration – WRONG
  5. The most important complication is intussusception – CORRECT

If the candidate has selected the answers number 1 and 2 as correct, the score will be as follows: Score = [1/2] – [1/3] = 0,16

Remember that the minimum score will be always 0.

 

How are the CORE cases scored?

 

Each CORE case has a maximum of 10 points. These 10 points are distributed among the questions of the case. Depending on their importance, the examiners may decide if some questions have more points than others.

A maximum of one case will be mandatory. This means that the candidate is required to complete this case to pass the exam. A mandatory case is identified by a label next to the case number on the left side of the screen:

 

A mandatory case has a special score called Unsafe. An unsafe score will be assigned when a catastrophic error (an error of observation, interpretation or management) which would have a major impact on the patient is made. An unsafe score will count as 0 when calculating the final score.

In order to pass this part of the exam, apart from having a score equal or higher than the corresponding pass-mark, it is required to fulfil the following minimum criteria:

  • The candidate must complete at least 8 out of 10 cases
  • At least 50% of the cases have 5 points or more
  • The candidate has at most one case with an unsafe score
  • If the candidate has one case with an unsafe score:
    • The candidate must not have any other case/s with 1,5 points or less
    • The candidate has failed at most one other case and their score in the CORE part is equal to or higher than the pass-mark in the CORE part + 5%. If so, it will be discussed by the EDiR Scientific Director and the CORE Committee Chair.
  • The candidate has at most two cases scored with 1,5 points or less

 

What if I do not agree with my score?

 

In case you do not agree with your score of the first component (WWS):

Since this part is automatically scored by the platform, an appeals process can only be made if there is a technical problem during the test.

In case you do not agree with your score of the second component (CORE):

You can start an appeals process of this part if the following criteria is made:

  1. The candidate fulfils the minimum criteria.
  2. The candidate has completed the 10 cases.

Any appeals must be requested within 10 days after the examination results have been sent. Please consult the terms and conditions, chapter XIII to know more about how to start an appeals process.
