The 1970 British Cohort Study (BCS70) assessed their cohort members (CMs) during the study’s age 10 sweep using the Spelling Dictation Task (SDT).
Details on this measure and the data collected from the CMs are outlined in the table below.
| Year of data collection: | 1980 |
| Domain: | Verbal (spelling) |
| Measures: | Dictation task measuring spelling and phonetic decoding |
| CHC: | Gc (Crystallised ability) |
| Ga (Auditory processing) | |
| Grw (Reading/Writing) | |

| Administrative method: | In schools; pen and paper |
| Procedure: | A paragraph was dictated to the child including both real and made-up words. A sentence could be repeated once and an imaginary word in the middle of the passage could be repeated twice. |
| Link to questionnaire: | No direct link to questionnaire. Instructions, including the dictated paragraph, can be found in file ‘a3723udb.pdf’ (page 26) accompanying data download from UK Data Service (link opens in a new tab). More information about the procedure can be found in the “Technical Resources” document below. |
| Scoring: | Maximum score of 50 where the child was awarded a point for each correct spelling of a real word and a score of 1 for each syllable of the made up words. |
| Item-level variable(s): | I3815 - I3864 |
| Total score/derived variable(s): | None |
| Age of participants (months): | Mean = 121.88, SD = 2.67, Range = 117 - 139 |
| Descriptives: | Raw score |
| N = 12,489 | |
| Range = 0 - 50 | |
| Mean = 34.96 | |
