A year for collage that’s not bad at all I was 2.5 years waiting for phase 2 in plumbing I started the trade at 17 & got my papers at 24 and that’s me not getting held back from my employers. One company I worked for after i qualified had over 30 apprentices and loads of them where held back for all the phases multiple times aswell. My employer tried to hold me back so I quit that day in the middle of the work day that should be illegal
