The AC-MT calculation abilities and problem solving evaluation test is a quick and easy tool for measuring mathematical abilities in pupils aged 6 to 11, which has good psychometric properties.
Compared to before this edition is characterised by new norms and new tests for pupils in the last three years of primary school. The test includes: pen and paper tests divided into 6 age groups (I intermediate and final, II, III, IV and V); individual tests for the 6 age groups; pen and paper problem solving tests divided into III, IV and V; norm reference scores obtained from a sample of 5000 subjects for specific, essential indexes (written operations, numerical knowledge, accuracy, total time, arithmetic problem solving). By allowing numerical abilities to be evaluated not only in reference to average, standard and percentage deviation, but also classifying them in 4 bands of performance (excellent, satisfactory, attention required, intervention required), the AC-MT test is the easiest and most effective tool on a national level for preventing and measuring learning difficulties in calculations at primary school.
The DVD-ROM which comes with the book contains: an example of test administration; Cesare Cornoldi’s comment on test evaluation and instructions for interpreting scores; printable test material in pdf format.
