Texas Success Initiative (TSI)
The Texas Success Initiative (TSI) is a state-legislated program designed to improve student success in college. There are two components of the program.
Students wishing to participate in dual credit classes during high school, or students preparing to graduate and go to college must pass the Reading, English (Writing), and Math sections of the TSI designated exam- the Accuplacer.
