Wilder Language and Learning of Boulder utilizes a unique and progressive evaluation model. We utilize the principles of dynamic assessment to best determine learning needs and to differentiate between language and learning differences, and language and learning disabilities. While traditional evaluation models only measure a client’s performance levels, at WLL we evaluate both the client’s performance and response rate, which provides the most accurate diagnostic information and intervention recommendations.  Response rate is measured by providing appropriate evidenced-based intervention at the necessary frequency, duration, and intensity and measuring the client’s response. It can then be determined if the rate of response of intervention (RRtI) is appropriate.

These evaluations adhere to the current public school special education eligibility criteria. 

Our evaluations are the most thorough method for determining a client’s performance levels, strengths, and areas of need, in addition to determining intervention strategies to which the client best responds. Response evaluations are also the only method that measure the rate of response of a client over time which is essential in determining the level and presence of a disability.

These evaluations allocate 18 sessions to provide intensive intervention in addition to gathering formal and informal assessment information. Performing evaluations over multiple weeks allows for flexibility to tailor the assessment to best meet the needs of the client while gathering both performance and response data.

  • 6 Evaluation Sessions
