Susan,
An excellent, detailed answer. The TWC CSC verifies the school's annual report in a number of ways such as calling students and employers, as well as comparing the report to the back-up data - including the required PS-072A for each student. The PS-072A must be completed by the school or the student (in the aggregate for each program) and must correspond to the data in the annual report.
Thank you,
