The MRC National Survey of Health of Development (NSHD) assessed their cohort members (CMs) during the study’s age 15 sweep using the Mathematics Test.
Details on this measure and the data collected from the CMs are outlined in the table below.
| Domain: | Verbal (arithmetic) | |
| Measures: | Mathematical ability/knowledge | |
| Mathematical achievement | ||
| CHC: | Gq (Quantitative Knowledge) | |
| Administration method: | Teacher; face to face; pen and paper | |
| Procedure: | Participants were administered a 47-item mathematics test, which tested arithmetic, geometry, trigonometry, and algebra. | |
| Duration: The total time of administration was approximately 30 minutes (25 minutes working time). Data were heavily positively skewed, indicating the test was too difficult. | ||
