Eligibility is the first check.
Each state and territory has an ordinary school-entry age rule. Some families have more than one lawful option; others do not. A developmental judgement cannot override compulsory-schooling requirements or grant an exemption.
Readiness is broader than age.
Families often think about participation in everyday routines, communication, relationships, attention, independence, play and learning. These are observations to discuss in context, not a checklist a child must pass.
Look at the setting, too.
A child's experience depends partly on the school environment and the support available there. Needing help is not, by itself, a reason to postpone school. Ask the school what adjustments and transition arrangements are possible.
Why include an educator?
Children may behave differently at home and in early learning. Separate parent and educator observations can show agreement, differences or areas where more information is needed. Neither automatically overrides the other.
What StartYear does not claim
StartYear's directional model has not been psychometrically or prospectively validated to predict the objectively best starting year. It is decision support, not a clinical or developmental diagnosis, school-readiness certification or substitute for professional advice.
