I'm assuming you want to measure their intelligence? You could use the WAIS (Wechsler Adult Intelligence Scale) IQ test. The WAIS can be used to measure performance in 4 domains of intelligence which are processing speed, working memory, verbal comprehension, and perceptual reasoning. You can look up more information about it to see if it will fit your needs.

Like Arielle, I could use more context to ensure I understand the question. The most obvious answer here is to use the SAT, ACT, GMAT, UGPA, and/or GRE for US based students. However, the goal is vital. For example, if you want to assess if they will be successful in an MBA program, I would recommend the following publications:
+ Siegert, K. O. (2008). Executive education: Predicting student success in executive MBA programs. Journal of Education for Business, 83(4), 221-226.
+Wilson, R. L., & Hardgrave, B. C. (1995). Predicting graduate student success in an MBA program: Regression versus classification. Educational and Psychological Measurement, 55(2), 186-195.
+ Hay, A., & Hodgkinson, M. (2006). Exploring MBA career success. Career development international, 11(2), 108-124.
+ Naik, B., & Ragothaman, S. (2004). Using neural networks to predict MBA student success. College Student Journal, 38(1).
+ Adams, A. J., & Hancock, T. (2000). Work experience as a predictor of MBA performance. College Student Journal, 34(2).
Business is an integrative domain of study, composed of many inputs coming from economics, management, marketing, mathematics, information technology, psychology, sociology, strategic thinking, law. Assessing the cognitive capability of business students depend on the purpose of assessment and of the university program in which they are (undergraduate, graduate, doctoral). Cognitive capability should incorporate also the capacity of integrating the knowledge received from different domains, as mentioned above. At the limit, the best evaluation would be students' capacity to initiate a real business and to develop it into an entrepreneurship process.
