The 1958 National Child Development Study (NCDS) assessed their cohort members (CMs) during the study’s age 11 sweep using the Mathematics Test.
Details on this measure (devised by the National Foundation for Educational Research) and the data collected from the CMs are outlined in the table below.
|CHC:||Gq (Quantitative Knowledge)|
|Administrative method:||Teacher at school; individually face to face; pen and paper|
|Procedure:||The test consisted of 40 items. The test included, number skills, fractions, measures and geometry. Most questions were calculated directly, with a few involving multiple-choice answers.|
