The 1958 National Child Development Study (NCDS) assessed their cohort members (CMs) during the study’s age 7 sweep using the Problem Arithmetic 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.
| Domain: | Arithmetic (arithmetic problems) |
| Measures: | Arithmetic |
| CHC: | Gq (Quantitative Knowledge) |
| Administrative method: | Teacher at school; face to face; self-completion. However, if necessary, each problem was read to the child if there was difficulty in reading the items. |
| Procedure: | Ten arithmetic problems graded in level of difficulty. In order to avoid penalising the poor readers, the teachers were asked to read the problems to the children if necessary. The test was discontinued after three successive incorrect answers. |
| Duration: It was expected 60 - 90 minutes would be required for all 4 tests at age 7. | |

| Scoring: | One mark was awarded for each correct answer, giving a score between 0 and 10 |
| Item-level variable(s): | Not currently available |
| Total score/derived variable(s): | N90 |
| Age of participant (months): | Mean = 85.11, SD = 1.56, Range = 82 - 93 |
| Descriptives: | Raw score |
| N = 14,897 | |
| Range = 0 - 10 | |
| Mean = 5.11 | |
| SD = 2.49 | |

| Other sweep and/or cohort: | None |
| Source: | The individual items were chosen in the main from a large number previously used by the National Foundation for Educational Research (NFER), so that information was available on their facility values and it was possible to select those items which on a 7-year-old population would produce a normal distribution of scores. |
