Knowledge Deficiency Report (KDR)
Immediately after completion of a PEXO exam, the Invigilator will provide each candidate with their Result Advice and, where appropriate, their Knowledge Deficiency Report (KDR) before they leave the exam centre. A KDR listing items answered incorrectly will be issued when a candidate’s result is less than 100% and more than 50%. If a candidate scores 50% or less in their examination, they will be referred to the entire syllabus.
A candidate, other than one for an ATPL flight test who has passed the exam should retain the RA/KDR, and present it to either the Head of Operations (HOO) or Examiner conducting the flight test for the licence or rating, or both, as the individual case may be. The HOO or Examiner, or both, will orally examine the candidate on the noted deficient areas of knowledge.
The KDR for a PPL, CPL, IREX or ATPL examination is issued with the Result Advice for a completed examination and lists the syllabus items the candidate has not answered correctly. Each listed syllabus item comprises:
- a text description of the item, and/or
- a paragraph number relating to the position of the item in the aeronautical knowledge component of the syllabus, hereafter called 'item number'. All KDR comments for pilot theory exams are referenced to Part 61 Manual of Standards, Schedule 3 and will include the unit within Schedule 3 and the specific item number, e.g.
- Smoking in aircraft - Part 61 MOS Unit 1.5.8 CFRC, 2.3.3 (e)
- Takeoff and landing separation minima - Part 61 MOS Unit 1.5.1 RFRC, 2.3.1 (c)
The KDR information provides the candidates, ground theory instructors, HOO or Examiner with a rapid means of identifying the syllabus item for re-studying and re-testing.
The number of syllabus items printed on the KDR in some examination types may not correlate directly with the published candidate's score as some questions carry more marks than others. Thus it is possible for a candidate with more KDR syllabus items to achieve a higher score percentage than one who has less KDR syllabus items in the same examination type.
The scored achieved by a candidate in an examination is assessed on submission. Only when the score has been determined, would the identification and publishing of the KDR syllabus items occur.
KDR without syllabus items
A candidate who obtains a 100% score in a CASA examination will not have any syllabus item on the KDR.
Similarly, a candidate who scores 50% or less will also not receive any specific syllabus items on the KDR. CASA considers a candidate who fails to achieve at least 51% as not being sufficiently trained nor prepared for the examination attempt. Such a performance requires a complete re-visit of the entire syllabus for the subject if re-training is contemplated. Therefore, a candidate who fails to achieve at least 51% in a CASA PEXO examination shall consider the entire syllabus for the subject material to restudy for the KDR.
Failing an examination is indicative of a candidate's knowledge deficiency. CASA requires the unsuccessful candidate to undergo adequate re-training before re-attempting the examination.
For detailed information on re-training period for the professional licence and rating examinations, see Re-training Requirements.
Replacement of KDRs
Should a candidate require a replacement KDR, this may be obtained either through the organisation which conducted the examination or from CASA. If the required KDR(s) pre-date PEXO (which came into effect on 24 September 2013) then they are only available from CASA. To obtain replacement KDRs from CASA, complete CASA form 059 (Form 059 Payment Advice - Flight Crew Licence Reports) and it will be sent to your postal address.
Please note: Replacement KDRs will not be sent electronically.
