Perth Children's House (PCH) is a Montessori method based Casa program serving children ages 31 months to 6 years. Our three year program is meant to instill a love of learning, self confidence and greater understanding in literacy, mathematics and the world at large. Children may start once they have reached the age of 31 months. However, they must start the program prior to the year of their 4th birthday, unless they are joining us from another Montessori school.
