The Occupational Aptitude Survey and Interest Schedule-Third Edition (OASIS-3) consists of two related tests: the OASIS-3 Aptitude Survey and the OASIS-3 Interest Schedule. The tests were normed on the same national sample of 2,005 individuals from 20 states. Teachers, counselors, and other professionals can easily use the OASIS-3 to assist in the career development of students in Grades 8 through 12 and adults. The OASIS-3 can be administered individually or in groups. Each test takes from 30 to 45 minutes to administer and can be hand-scored or machine scored.
