ALEKS is a powerful artificial-intelligence based online assessment tool that zeros in on the strengths and weaknesses of a student's mathematical knowledge, reports its findings to the student, and then if necessary provides the student with a learning environment for bringing this knowledge up to an appropriate level. The University of Arizona Department of Mathematics is currently using the ALEKS assessment tool for placement into all of its entry-level courses.

The ALEKS assessment covers a broad spectrum of algebra or pre-calculus material. The ALEKS system is fully automated and the ALEKS assessment is adaptive. The first questions asked will be drawn from across the curriculum, and may be too easy or too hard. As the assessment proceeds, your answers will be used to give the system an idea of your knowledge, and it will gradually focus the questioning in an individually appropriate way. By the end of the assessment you should find the questions generally challenging but reasonable for your individual level of knowledge.
