AUSTIN, Texas (AP) — Administrators are trying to determine whether some students in Texas taking an online standardized test lost answers in a computer glitch.

The Texas Education Agency says the vendor, Educational Testing Service, is working to determine what went wrong Tuesday. The TEA is trying to figure out how many districts were affected, amid reported problems in the Austin, Bryan and Arlington areas.

Students must pass the State of Texas Assessments of Academic Readiness to graduate from high school. More exams were scheduled Wednesday.

Officials with ETS, in its first year of handling most of STAAR, believe its computer server has saved the answers.

Some districts reported questions answered but results later gone. The trouble was found when students logged back on or they were logged off after 30 minutes of inactivity.
