The Calculation Fluency Test (CFT) was developed in the Math Cognition Lab at Carleton University. It was modeled on two sub-tests of the French Kit of Cognitive Factors (French, Ekstrom, & Price, 1976), a set of various measures of mental processing. The original tests included an Addition Sub-test comprises rows of three-term addition problems (arranged vertically) and a Subtraction/Multiplication sub-test has alternating rows of double-digit subtraction problems and double times single-digit multiplication problems.
The revised version included here has three pages, one of addition, one of subtraction, and one of multiplication. Further information about test development can be found in the Technical Report.
