The Career Interest Inventory (CII) is a career-guidance instrument designed to provide information about students' educational goals, interest in a variety of school subjects and school-related activities, and interest in fields of work. This information helps students explore educational and occupational alternatives, learn about careers, and set goals for the future. The Career Interest Inventory was standardized with the Differential Aptitude Tests®, Fifth Edition (DAT®), providing students' aptitude and interest comparisons when the two tests are given together.

The Differential Aptitude Tests®/Career Interest Inventory Scoring Assistant (DAT®/CII Scoring Assistant) facilitates scoring of the DAT, Form C and Career Interest Inventory.

The Differential Aptitude Tests®, Fifth Edition (DAT®), provides a valid and reliable assessment tool for course and career selection. It measures students' abilities in verbal reasoning, language usage, numerical reasoning, mechanical reasoning, and space relations. The Counselor's Report, available from combined administration of DAT and the Career Interest Inventory, provides an effective starting point for career discussion with counselors, parents, and students. Level 1 is primarily for students in grades 7 through 9; Level 2 is primarily for students in grades 10 through 12 and adults. Both levels can be used with basic adult education, community college, vocational/technical, and correctional programs.
