Identification of mathematical difficulties: validation and French-Quebec normalization of the Tempo Test Rekenen and the Numeracy Screener French version

Abstract

The aim is to investigate the psychometric properties of two mathematical tools in order to receive French-Quebec normative data for the screening and identification of children at-risk for mathematical learning disabilities: the Tempo Test Rekenen (TTR) that assesses arithmetic fluency and the French version of the Numeracy Screener (NS-f) that assesses the basic skills of number and numerosities processing. These tests were administered to a total of 695 francophone children in Quebec from kindergarten to 6th grade. Results showed good internal consistency, predictive validity, and construct validity. Results thus suggest that the set of NS- f and TTR has good validity for screening and identifying children at-risk for mathematical learning disabilities.
