My guess: Driver had 1 critical driving error, as noted on lower left of form. Zero are allowed, see top center of form, second line under "driving performance evaluation score sheet". Details are in "comments" section (bottom center of from) starting with "CDE (critical driving error)left turn #2"
also noted in comments is a second error, driver failed to yield on a right turn.
I only see 3 errors marked in maneuvers. it takes 15 of these to fail.
Study the 5 checked area of "driving improvement checklist" on the right side of the form, and try again
