Implementation details

Respondent Child
Prior knowledge Required NIEFER representatives offer support and guidance to teachers implementing the ELS.
Scoring Reported as manageable and accessible to all teachers
Time Effective assessment requires teachers to observe children over time and in varied situations.
Age 3 years to 5 years

Psychometric details

UK norms NO
Norm / Criterion referenced Criterion referenced
Standardisation sample 276
Reliability 71 to 98% for a sample of 57 teachers in New Jersey and 73.5 to 77.6 % for a sample of 29 educators in South Dakota. Internal consistency: Cronbach's alpha of .91.
Criterion validity Insufficient data in the public domain to evaluate
Construct validity Measures a single construct
Concurrent validity Concurrent validity with ELSA, the total ELSA raw score and the total ELS Language arts/Literacy score correlated moderately at .36. The total math/science ELS and the CMA total score correlate significantly at .46. Size of these associations varied based on domain. The correlation coefficient between ELS and direct assessment of similar constructs range from .17 to .52. Children’s math and language and literacy scores as assessed by ELS were similar to their scores in direct assessment in those domains: WJ10, PPVT, and WJ1 respectively. The strongest association was found between ELS Language and WJ 1 Letter-Word Identification score (r = .52, p < .001). Children’s science as assessed by ELS was not as similar to its direct assessment assessed by PSA, though it was significant statistically (r = .17, p < .01).
