I am teaching using John Thompson's piano course for adults for the first time and would like to know what standard, in terms of grades, pupils are at by the end of the book.
there's 2 books I think
if it's this one: John Thompson's Modern Course for the Piano
then it can be up to grade 3 because you go up to Ab major as well as know some more advanced hand positions
if it's this one: John Thompson's Adult Piano Course
it's probably mid level 2 because you don't get the hand positions
