Final answer:
Norm-referenced testing is problematic in young children with suspected autism due to the unavailability of tests for the 0-3 age group, the impact of social impairment on performance, the emergence of symptoms at age three, and the limited understanding of normal development.
Step-by-step explanation:
Norm-referenced testing is problematic in young children with suspected autism for several reasons:
- Tests specifically designed for the 0-3 age group are not widely available, making it difficult to accurately assess their abilities.
- The social impairment often associated with autism can impact a child's performance on norm-referenced tests, as they may struggle with tasks that involve social interaction or communication.
- Autism symptoms typically do not fully emerge until around age three, making it challenging to diagnose and assess younger children accurately.
- Normal development in young children is not well understood, which makes it difficult to establish appropriate norms for comparison.
Overall, these factors contribute to the challenges of using norm-referenced testing with young children suspected of having autism, highlighting the importance of considering alternative assessment methods that are better suited to their unique needs.
