The TSI Assessment 2 (TSIA2) is part of the Texas Success Initiative program designed to help colleges and/or universities determine if students are ready for college-level course work in the areas of Reading, Writing, and Mathematics. If you are planning on taking dual enrollment courses at Jimmy Carter, you must master the examinations to take South Texas College (STC) courses.
The American College Testing (ACT) Exam measures your achievement in core academic areas that are important for college and career success: English, Math, Reading, Science, and (optionally) writing. It isn't an IQ test--it doesn't measure your basic intelligence. It's an achievement test that's been carefully designed to be one of the tools for evaluating your college and career readiness.
The Scholastic Assessment Test (SAT) is developed by the College Board. College Board test developers are content experts in their respective disciplines and use their expertise to create questions for the SAT that will allow students to demonstrate their best thinking. Colleges use the SAT in admissions because it's developed according to rigorous specifications, with input from numerous experts, to assess what matters most for college and career readiness and success.
AP Exams are college-level tests administered by The College Board based on subject areas. Students take AP exams in May and receive their scores in July. Exams are given a score of 1 through 5, with the score of a 3 typically earning students college course credit in the tested subject area. Top tier universities tend to only accept AP scores of 4 and/or 5.
AP exams are not directly related to college admissions, but AP courses and AP scores do look good on a college applications since the exam's function is to determine college credit or course placement.
