The Millennium Cohort Study (MCS) assessed their cohort members (CMs) during the study’s age 3 sweep using the Bracken School Readiness Assessment-Revised (BSRA-R).
Details on this measure and the data collected from the CMs are outlined in the table below.
| Domain: | Basic knowledge in preparation for school | |||
| Measures: | The BSRA-R is used to assess the 'readiness' of a child for formal education by testing their knowledge and understanding of basic concepts. The cohort members completed six sub-tests of the BSRA-R: | |||
| 1. Colours: represents both primary colours and basic colour terms. | ||||
| 2. Letters: measures knowledge of both upper- and lower-case letters. | ||||
| 3. Numbers/Counting: measures recognition of single- and double-digit numbers, and samples the ability to assign a number value to a set of objects. | ||||
| 4. Sizes: includes concepts that describe one, two, and three dimensions. | ||||
| 5. Comparisons: measures ability to match and/or differentiate objects based on one or more of their salient characteristics. | ||||
| 6. Shapes: includes one, two, and three-dimensional shapes. The one-dimensional category includes linear shapes; two-dimensional shapes are represented by concepts such as the circle, square, and triangle; and three-dimensional shapes include concepts such as the cube and pyramid. | ||||
| All sub-sets are designed to measure 'readiness' concepts which a child should have mastered before they commence formal education. | ||||
| CHC: | Gc (Crystallised ability) | |||
| Gv (Visual processing) | ||||
| Gq (Quantitative Knowledge) | ||||
| Administrative method: | Interviewer; face to face: non-verbal and interviewer records on CAPI | |||
| Procedure: | The exact tasks varied but, in essence, the cohort members were shown a page containing a number of visual stimuli, and were asked to point to the one that matched what the interviewer?s read out. The CAPI script managed the scoring system for the assessments, which determined when one sub-test was terminated and the next one begun, based again on the patterns of correct and incorrect answers. (Unless the interviewer over-rode the script), each cohort member attempted at least some of each of each sub-test. Interviewers also had the option, based on how the cohort member was reacting, to terminate any sub-test, or the whole assessment, at any time. | |||
| Duration: 10 - 15 minutes | ||||

| Scoring: | 88 items in total, 6 sub-sets with varying number of items. 1 point for each correct response and 0 for incorrect response. Raw scores are provided for each sub-scale and are added together to provide a composite raw score, known as the School Readiness Composite (Bracken, 1998). To account for the differing number of items within each of the subscales, a percentage score (raw score relative to the number of items) score is also provided. In addition to the raw total score, there are also age-adjusted standardised scores (based on a US norming sample), percentiles and a normative classification which categories scores into a grouping based on the standardised composite score. | |||
