About Us

TSI Prep offers free preparation materials for students preparing for The Texas Success Initiative Assessment (generally referred to as the TSI exam).

Our practice tests and guides are carefully researched and adjusted to the needs of students.

Texas is our home and we aim to contribute to The 60x30TX (“60 by 30 Tex”) higher education strategic plan: “By 2030, at least 60 percent of Texans ages 25-34 will have a certificate or degree.”

Tsi Prep is managed by Onsego, Ltd. We are an independent online publisher and we are located in Richardson, Texas.
