About the Measure
| Domains | Omnibus |
| Subscales | Phonological awareness, literacy and language |
| Target Construct | Literacy: Listening, rhyme recognition and production, alliteration, detection of words within sentences, word segmentation into syllables and onset rime, and early writing skills. Numeracy: Counting, shape naming, operations, number identification and shape discrimination. Social emotional: Positive social behaviours, classroom community and safety, emptions and behaviour regulation, self-care and attention. |
| Description | This is not a diagnostic or norm- referenced measure. It is a standardized, criterion-referenced measure that includes individually administered screening and progress monitoring measures designed to efficiently evaluate and monitor growth of preschool children’s school readiness skills. |

Psychometric details
| UK norms | NO |
| Norm / Criterion referenced | Criterion referenced |
| Standardisation sample | Four studies 37,731 |
| Reliability | Cronbach's alphas for PA are greater than .90 for all age groups. Test retest ranged .47 to .68 for vocabulary, .62 to .83 for letters and .50 to .75 for PA. Internal consistency was .81 for maths and test retest was .82 for maths. Internal consistency was .96 for Social emotional. |
| Criterion validity | The vocabulary test measured on the CIRCLE correlated with the Expressive One Word Picture Vocabulary Test (EOWPVT), which is a standardized measure of vocabulary. Letter naming in the CIRCLE correlated with the Preschool Comprehensive Test of Phonological Processing and Print Awareness (PreCTOPPP) Print awareness subscale. Phonological awareness and the component subtests correlated with Developing Skills Checklist (DSC) and PreCTOPPP measures of blending and elision. A strong correlation between children’s science scores and Preschool Science Assessment (PSA; Greenfield et al., 2013) total raw scores (r = .84) and PSA standard scores (r = .81) |
| Construct validity | Correlations of .64 to .90 with other measures of expressive language, measures of other areas of language development, academic achievement, and general cognitive ability |
| Concurrent validity | Correlations of .64 to .90 with other measures of expressive language, measures of other areas of language development, academic achievement, and general cognitive ability |
