Many learners enter formal schooling without having mastered the necessary school readiness skills. Academically, those who are not equipped with the necessary school readiness skills often experience certain difficulties, a situation that can even lead to failure at the end of their first year at school. Had these learners been assessed for school readiness earlier, and their teachers informed of the interpreted results, they could have been helped to improve their literacy level earlier. With their knowledge, teachers are able to provide appropriate additional support to meet identified school readiness needs. A concern amongst educators is that many school readiness assessment instruments are available but they do not test the same skills. A further issue is that scientifically proven criteria for evaluating school readiness assessment instruments are not known to be available. Using information about the skills being assessed according to helpful and insightful criteria, would enable educators to know how best to assist learners. Learners do progress and learn differently. Focusing on the skills needed to succeed at school is essential for learners’ development. Hence the reason for engaging in this research was to explore school readiness assessment. From semi-structured interviews conducted, Grade 1 teachers did not have detailed knowledge of school readiness assessment and the instruments used. It is therefore recommended that awareness of the criteria for successful school readiness assessment becomes an integral part of the preparation for formal schooling. Irrespective of their age, applying such instruments could help learners who are not yet ready for school to be better prepared pre-schoolers.
