I am a speech pathologist currently working in a preschool/kindergarten building. I often use the CELF-Preschool 2 or the CELF-4 to evaluate their communication skills. I would like this question directed to the authors of these assessment tools. Since both of these tests cover the 5-6 year age range, which test would they recommend we use at the kindergarten level?
In general, the CELF Preschool-2 is your best option for children in Kindergarten–the formats in the test are more supportive and child-friendly for young children. This is especially the case if a child is a young five year old (e.g., 5:0 through 5:5) and has had little preschool experience, and limited verbal ability. There is more in-depth content coverage for younger children in CELF Preschool-2 than you will find on CELF-4, which covers content for mostly older children (ages 5-8).
Keep in mind that if the children you are testing in Kindergarten are five years old, have enough preschool experience that they are comfortable and familiar with school types of tasks, and express themselves well in social situations, you will be able to obtain accurate test results using the CELF-4. Your choice of assessment really depends on the maturity of the child, previous preschool experiences, social verbal ability, and his or her experiences with standardized assessment tools.
