I personally endorse the CLII. I particularly like the CLII Occupational Interests that supplement the Holland’s RIASEC model, helping to further narrow down students’ interests. This is what sold it for me years ago. For example, my lowest score is Investigative, yet I am a professional counselor. This seemed disconnected for me until I looked deeper into the supplemental Occupational Interests, which also indicated that my behavioral science Interest was very high. Overall the CLII is quick, inclusive, cost-effective, and uncomplicated. I would recommend the CLII for students, school or career counselors, and those in career transition.
