The Residual ACT is an on-campus or "residual" testing program. It is available at The University of Alabama in Huntsville to students who were unable to test on an ACT National Testing date. ACT Residual Testing is strictly limited only to UAH students who have enrolled, have been admitted, or have officially applied to UAH. Scores from residual testing are reported only to UAH for admission, course placement, and advising purposes. No scores will be sent to other institutions or organizations. For more information on applying for admission to UAH, visit UAH Office of Admissions. It is a pencil and paper test. It follows the same format as a regular ACT administration.
