Which of the following standardized tests is recognized for assessing students in Texas?

The ITBS, or Iowa Tests of Basic Skills, is recognized for assessing students in Texas primarily because it is designed to evaluate academic skills and knowledge in various subjects for students from kindergarten through eighth grade. This test has been utilized in Texas and is aligned with state educational standards, making it a suitable choice for school districts seeking to measure student progress and proficiency.

On the other hand, while the PARCC (Partnership for Assessment of Readiness for College and Careers) serves as an assessment tool in various states, it does not specifically apply to Texas. The ACT is primarily a college entrance examination focusing on high school students preparing for higher education rather than assessing progress in the K-12 public school system in Texas. The AP Exams are designed to assess students' proficiency in college-level material and grant college credit; however, they do not function as standardized assessments for measuring general academic achievement across the K-12 spectrum in Texas public schools.

Thus, the ITBS is the most appropriate assessment in the context of standardized testing for students in Texas.
