Yes, IAA require it. I have just gone back instructing after 4yrs, when I last instructed in 2011 I think an elp 4 was automatically issued with the students licence and the elp 6 when the PPL was issued after the flight test. Now students have to take an elp test before their first solo even if they are native English speakers, Ridiculous.It isnt stated as a requirement in part fcl.
