Methods of Pre-school Education
In many areas, private classes are offered for children aged from six months to three years. These combine the theory and practice of play groups and day care centres. Many areas also have what are termed ‘toddler’ or ‘tot’ programmes, which usually accept children from two to four years of age. Activities generally include arts and crafts, music, educational games, perceptual motor activities and listening skills. Most communities also have informal community schools or learning centres, playgroups, morning programmes at local YWCAs, and other inexpensive alternatives to private schools. Community colleges also offer a variety of courses for small children, e.g. painting, dancing and cooking, once or twice a week, e.g. on Saturday mornings.
Many children attend private nursery schools for two to six-year-olds and some private elementary schools have a pre-nursery or nursery programme. Fees for private nursery schools range from $5,000 to $15,000 per year for full-time schooling, depending on the school and area. School hours vary, but children usually attend for a few hours in the morning, e.g. from 9am to 11.30am, or afternoon, e.g. 12.45pm to 3.15pm, or both. Some schools allow you to choose a number of morning or afternoon sessions only, thereby reducing the fees. Many day care centres are designed for working parents and combine nursery school and (extended) day care, with centres open from 6.30am to 6pm.
