In accordance with FCL.1030:
(a) When conducting skill tests, proficiency checks and assessments of competence, examiners shall:
(2) verify that the applicant complies with all the qualification, training and experience requirements in this Part for the issue, revalidation or renewal of the licence, rating or certificate for which the skill test, proficiency check or assessment of competence is taken;
This implies that if you are including an AoC as one of the revalidation items, all requirements for revalidation are completed prior to completing the AoC. The UK CAA acknowledged that this was not practical in the case of an FI and allowed the items in any order however; other States may have different ideas.
