TSI Registration at Johnson has closed. Any student still needing to retest for a section of the TSI test will have to contact one of the Alamo Colleges Assessment centers and schedule an appointment. Students have until Friday, June 9, 2017 to complete a retest and qualify for their Dual Credit classes for 2017-2018 school year. If you qualify for a TSI Exemption, then you will not need to take the TSI. TSI Exemptions are related to SAT scores and ACT scores. Please review the Test Score Chart above to see the specific requirements for any Dual Credit class.
