I find that remark completely incomprehensible.
JAR introduced terminology that was misread by many. A Proficiency Check was used for Revalidation but; a Renewal required a Skill Test. The content of the two were exactly the same, consequently many incorrectly assumed that the Skill Test was the Licence Issue Skill test; two completely different tests, albeit there are some similarities!
EASA has had the good sense to redefine Proficiency Check
‘Proficiency check’ means the demonstration of skill to revalidate or renew ratings, and including such oral examination as may be required.
and Skill Test
‘Skill test’ means the demonstration of skill for a licence or rating issue, including such oral examination as may be required.
BB's point is that since the introduction of JAR 13 years ago, the license issue Skill Test has formed no part of the Revalidation or Renewal process.
