The 1970 British Cohort Study (BCS70) assessed their cohort members (CMs) during the study’s age 5 sweep using the Schonell Reading Test (SRT).
Details on this measure and the data collected from the CMs are outlined in the table below.
| Year of data collection: | 1975 |
| Domain: | Verbal (reading) |
| Measures: | Children's reading age (of children between age 5 and 14+ years). Reading age is calculated from the number of words read correctly and compared to the child's chronological age. |
| CHC: | Gc (Crystallized Intelligence) |
| Grw (Reading/Writing) | |

| Administrative method: | Health visitor at home; face to face; read aloud |
| Procedure: | Before the test was administered, the child's mother was asked if she thought the child had begun to read at all. If the mother said the child could read some words or some sentences the child was given a card with 50 words on it, which were read from left to right. When a child struggled with a word, they were asked to sound it out. If the child still couldn't say what the word was, they were asked to try the next one. The test was stopped when the child made five consecutive mistakes. |

| Scoring: | 50 words (first of original 100). Score of one for each word read correctly. |
| Item-level variable(s): | f099 (can the child read 68% (8,603) could not read or could only read some letters) |
| Total score/derived variable(s): | f100 (correct responses) |
| f101 (incorrect responses) | |
| Age of participant (months): | Mean = 61.78, SD = 1.33, Range = 60 - 77 |
| Descriptives: | Raw score |
| N = 12,646 | |
| Range = 0 - 50 | |
| Mean = 1.43 | |
| SD = 3.87 | |
