OASIS-3:AS - Occupational Aptitude Survey and Interest Schedule — Third Edition

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.

Aptitude Survey
The OASIS-3 Aptitude Survey measures six broad aptitude factors that are directly related to skills and abilities required in more than 20,000 jobs listed in the Dictionary of Occupational Titles. The Aptitude Survey yields six scores: General Ability, Verbal Aptitude, Numerical Aptitude, Spatial Aptitude, Perceptual Aptitude, and Manual Dexterity. Validity coefficients with similar subtests of the General Aptitude Battery range from .60 to .80. Median alpha reliabilities range from .70 to .91. Each Aptitude Survey kit can test up to 50 students in groups of 10.

Interest Schedule
The OASIS-3 Interest Schedule measures 12 interest factors directly related to the occupations listed in the Guide of Occupational Exploration. The factors are Artistic, Scientific, Nature, Protective, Mechanical, Industrial, Business Detail, Selling, Accommodating, Humanitarian, Leading-Influencing, and Physical Performing. The Interest Schedule contains 240 items scored as Like, Neutral, or Dislike. Alpha reliabilities range from .83 to .96. Construct validity was determined through principal components analysis and empirical research.
