The developmental stages in this progress checker have been produced by speech and language therapists based on research and their knowledge of communication development. They have been cross-referenced by I CANs speech and language therapists against a range of sources including:
'Language Development Milestones' edited by Nicole Sax and Erin Weston
- 'Living Language Checklists' by Ann Locke
- The Queensland language checklists
- Reynell Development Language Scales Reynell, J. & Gruber, C. (1990).
- Speech and Language Development Chart (2nd ed.) Gard, A. Gilman, L. Gorman, J. (1993).
- This Progress Checker has been written by speech and language therapists, based on typical developmental milestones
- It is intended to be used as a guide only. No diagnosis can be made as children are not seen face to face.
- It is possible that concerns may be highlighted when there are not issues with children’s speech and language. If in doubt, check with a health visitor or speech and language therapist.
- If your child has just had a birthday, you might want to look at the age-group younger than them. Similarly, if your child is coming up to a birthday, you might want to check the age-group older than them.
If you are concerned about your child's development, an assessment by a speech and language therapist is the only way to be sure. Find your local speech and language therapist here.”
