Abstract

Background: The Early Learning Outcomes Measure (ELOM) assesses early learning
programme outcomes in children aged 50-69 months. ELOM assesses gross motor development
(GMD), fine motor coordination and visual motor integration (FMC & VMI), emergent
numeracy and mathematics (ENM), cognition and executive functioning (CEF), and emergent
literacy and language (ELL). Content and construct validity, reliability and cross-cultural
fairness have been established.
Aim: To establish the test-retest reliability and concurrent validity of the ELOM.
Setting: Low income preschool and Grade R children.
Methods: In study one, Test-retest reliability was investigated in a convenience sample of 49
English and isiXhosa speaking preschool children (Mean age = 60.77 months, SD = 3.70) tested
and retested one week apart. In study two, concurrent validity was investigated in a
convenience sample of 62 children (Mean age = 75.05 months, SD = .75). ELOM performance
was compared with that on the Wechsler Preschool and Primary Scale of Intelligence Fourth
Edition (WPPSI-IV).
Results: Test-retest reliability was established for ELOM Total score (r = .90, p < .001). The
concurrent validity of ELOM Total and the WPPSI-IV Full Scale Composite scores was
established (r = .64, p < .001). FMC & VMI, CEF, and ELL domains correlated significantly with
their corresponding WPPSI-IV indices: visual spatial, fluid reasoning, processing speed,
working memory, and verbal comprehension.
Conclusion: The findings of both psychometric studies contribute further to the reliability and
validity of the ELOM.
Keywords: concurrent validity; ELOM; WPPSI-IV; test–retest reliability; preschool.
