Here is an easy to use communication questionnaire for students with developmental delays and autism. The questionnaires supply a wealth of information from parents and teachers to help assess functional communication and early language skills. Use the results to help write your PLAAFP and functional IEP objectives.
The questionnaires focus on functional communication skills such as core vocabulary words and social interaction skills.
Pair this questionnaire with my Photograph Assessment of Early Language Skills (PAELS) for a thorough informal assessment (https://www.teacherspayteachers.com/Product/Photograph-Assessment-of-Early-Language-Skills-Early-Childhood-Autism-Speech-921161)
