The Hong Kong Early Child Development Scale (HKECDS) is a tool for assessing holistic early child development in preschoolers aged from three to six years. The original version of the scale, HKECDS, was updated in 2019 (HKECDS-2) to reflect the contemporary context and local curricular expectations. Children (n = 144) from three kindergartens in Hong Kong completed the HKECDS-2 in individual sessions. Rasch model analysis and expert discussions resulted in a short version of the scale (HKECDS-3) with 50 items in nine domains. The domains are Personal and self-care (4 items), Language development (7 items), Pre-academic learning (10 items), Cognitive development (6 items), Gross motor (4 items), Fine motor (2 items), Health and safety (5 items), Moral development (6 items), and Society and environment (6 items). There were significant correlations between findings from the updated version of the tool, HKECDS-3 and the HKECDS-2 (long form), and older children had significantly higher scores than younger children. Copyright © 2022 by THE PACIFIC EARLY CHILDHOOD EDUCATION RESEARCH ASSOCIATION.

Demand for second-language (L2) Chinese education for kindergarteners has grown rapidly, but little is known about these kindergarteners' L2 skills, with existing studies focusing on school-age populations and alphabetic languages. Accordingly, we developed a six-subtest Chinese character acquisition assessment to measure L2 kindergarteners' abilities to make associations among the forms, sounds, and meanings of 40 Chinese characters, and administered it to 173 five- and six-year-old L2 kindergarteners in Hong Kong. We found a high model-to-data fit using the two-parameter logistic item response theory model (MSsubscript infit] = 0.87 to 1.07, ps > 0.41). Of the 40 items, 36 exhibited a range of difficulty and good discrimination. Internal consistency reliability and inter-rater reliability were also high. The children scored highest in the category of meaning-sound associations, followed by mapping from meaning to form. The results demonstrate that the instrument is adequately valid and reliable for assessing L2 kindergarteners' character acquisition and imply that child L2 learners may develop abilities to map meanings and sounds prior to their development of form-related mapping. With minor modifications, the developed instrument can be used in various child Chinese L2 programs around the world. Copyright ©Sage Publications Ltd.
