The Galileo G3 Assessment Scales for preschool children provide a detailed sequence of goals which children are likely to master during birth to five years of age. These scales are split into five age ranges, 00-08 months, 08-18 months, 18-24 months, 2-3 years and 3-5 years. The developmental sequences in Galileo G3 Assessment Scales for infants and toddlers provide an overall picture of the order in which learning is likely to occur. This picture can be used to guide the kinds of learning opportunities provided to children. The following documents provide a listing of what capabilities the average preschoolers are likely to learn during each age range. You will see a developmental progression of easy to more difficult skills reflected in each document.
