these license endorsements can be found in:
The application for the issue, revalidation or renewal of an OJTI, STDI or Assessor endorsement can be made on CAA
Form SRG 1415.
Unit endorsements are valid for 12 months unless otherwise authorised by the CAA.
OJTI, STDI and Assessor endorsements are valid for 36 months.
If expired, your OJTI, STDI or Assessor endorsement will not appear on your licence, but it is kept on record and
will be added to your licence again after successful renewal.
To be granted an OJTI endorsement you must:
To be granted an Assessor endorsement you must:

An assessor endorsement only entitles the licence holder to conduct assessments in accordance with ATCO.C.045. The evaluator/verifier system for a Unit Training Plan is a UK-specific system which permits an OJTI who has successfully completed an evaluator course to make judgements as to whether a trainee can progress on the Unit Endorsement Course. This should ensure independence of the Unit Endorsement Course from the final assessment to gain the Unit Endorsement.
If you are applying for the issue of an Assessor endorsement:
If you are applying for the issue of an OJTI endorsement, sections 1, 2, 4 and 7 of SRG 1415 should be completed.
To renew or revalidate either of the above endorsements:
A refund fee may be charged if the application is found not to be in order and results in the rejection of your application. This will also be applied if you choose to cancel your application.
Regulation 2015/340 AMC1 ATCO.AR.D.001(a) Procedure for the issue, revalidation and renewal of licences, ratings, endorsements and authorisations states that the CAA may allow the privileges of a licence to be exercised for a period of eight weeks after successful completion of the applicable examination(s) and assessment(s), pending the issue of the licence, rating or endorsement.
The CAA may allow this grace period to be used (which is only to allow the CAA processing time of the licence), however this will only commence once the applicant has received an acknowledgement of their application back from the CAA.
It is not to be assumed that this will automatically be given. CAP 1251 will be updated in due course.
