Item analysis and revisions were confirmed with consensus agreement. It was piloted and later administered by 28 teachers. The accuracy of findings by teachers and the tool's internal consistency were evaluated. Concurrent validity was confirmed with criterion\u2010standard assessments by a developmental paediatrician. Psychometric properties were assessed using the Kuder\u2013Richardson 20 (KR\u201020) and kappa statistics. Cut\u2010offs for fine motor, gross motor, receptive language, expressive language, social\u2013emotional, and pre\u2010academic were derived using receiver operating characteristic curve analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The tool was administered on 597 children. The accuracy of findings by teachers was 100% for all domains. All KR\u201020 values for 3\u2010 to 4\u2010year\u2010olds were greater than 0.7 except for fine motor (0.629). All KR\u201020 values for 4\u2010 to 5\u2010year\u2010olds were greater than 0.7 except fine motor (0.683) and social\u2013emotional (0.694). The sensitivities for all domains were greater than 0.7 except for receptive language and social\u2013emotional in the 3\u2010 to 4\u2010year\u2010olds and for expressive language and pre\u2010academic in the 4\u2010 to 5\u2010year\u2010olds.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interpretation<\/jats:title>\n                    <jats:p>Acceptable sensitivity for most items in this iteration of the REACh will enable screening and referral to services.
