One analogous test in mathematics is the <A HREF="https://link.springer.com/article/10.1007/s40753-016-0030-5">Function Concept Inventory</A> test, designed to investigate undergraduate students’ understanding of the concept of function. Another is the <A HREF="https://www.physport.org/assessments/assessment.cfm?A=PCA">Precalculus Concept Assessment</A> to "assess essential knowledge that mathematics education research has revealed to be foundational for students’ learning and understanding of the central ideas of beginning calculus." A third is the <A HREF="https://www.ams.org/notices/201308/rnoti-p1018.pdf">Calculus Concept Inventory</A>, to assess "the most basic principles of differential calculus". A fourth is the <A HREF="http://sigmaa.maa.org/rume/crume2018/Abstracts_Files/Submissions/75_Development_of_the_Elementary_Algebra_Concept_Inventory_for_the_College_Context.pdf">Elementary Algebra Concept Inventory.</A>
