Exam

There are four levels of exams: “A”, “B”, “C”, and “D”. Each exam is allotted three hours and consists of 100 multiple choice questions with 70 percent correct being the minimum required to pass. Those wishing to take the exam may do so at the T.W.U.A. Annual School, each of the T.W.U.A. Regional Schools, or on Fridays by appointment, at the T.W.U.A. Central Office (888/367-8982)or (512/459-3124) in Austin. Appointments should be made at least two weeks in advance of the date you would like to test. Results are mailed to the examinee within four to six weeks from the date of the exam and includes a personal diagnostic profile. Should you not pass, there is a two month waiting period before an exam may be retaken. You are allowed one free retest, if you retest within six months of the original test date and at the same certification level. Upon successful completion of an exam, a certificate will be issued by the T.W.U.A. Laboratory Analysts Section.  For more information on this section please visit their website at http://www.txlas.net.
