The AC-MT 11-14 is an extremely important mathematical ability evaluation test, as it is one of the few tools in Italy which is capable of evaluating calculation and problem-solving abilities in youths aged 11 to 14. It is an easy-to-use test, which enables different aspects of mathematical learning to be separately evaluated:  written and oral calculation abilities, skills in understanding and producing numbers, arithmetic reasoning abilities, calculation speed and problem solving skills. Originating as a follow-on from the AC-MT test, for children aged 6 to 11, this evaluation tool is extremely precise, as it has been standardised on a wide sample of over 2600 youths.
