摘要：The purpose of this study was to construct a rating scale of infant and toddler development for the use of teachers in their observations of children during daily activities. The scale consists of 201 items measuring motor,self-help,socio-communicative,socio-emotional,and cognitive development. Quality,reliability and validity were examined with the use of a nation-wide sample of 1,245 children from classes of 1- and 2-year-olds. Tests on validity and reliability were high in terms of content validity evaluated by early childhood professionals,concurrent validity with the Bayley Scale,internal consistency among raters,and test-retest reliability. Factor analysis showed that the developmental areas of infants and toddlers are not clearly differentiated but are interrelated with each other. The scale was standardized by providing nation-wide norms with raw scores,percentiles,and standardized scores..
