Abstract
The Developmental Indicators for the Assessment of Learning is a screening test to identify children at risk of developmental delays and academic problems. The present study investigates the psychometric properties of the Developmental Indicators for the Assessment of Learning among children. The statistical population included children from 2 years and 6 months to 6 years in Tehran and Bojnord cities, and the sampling was done cluster random from kindergartens in Tehran and Bojnord cities. The final sample number was 336 children. Based on the interviews and preliminary implementation of the test, the general result was that the test is generally relevant and appropriate for the assessment of learning in pre-primary school age in Iran. The overall difference between age levels in motor, concepts, language, self-help development, and social-emotional development sub-tests was significant (p<0.0001). Considering the desirability of the fit indices, the factorial structure of the Developmental Indicators for the Assessment of Learning was confirmed. Regarding the simultaneous validity, the correlation between the Developmental Indicators for the Assessment of Learning and Denver Developmental Screening Test was established. The reliability of Cronbach's alpha for motor, concepts, and language subtests was 0.94, 0.95, and 0.94, respectively. Therefore, the Developmental Indicators for the Assessment of Learning to evaluate Iranian children have acceptable validity and reliability.
