Assessment Division at 610-649-1119

The Assessment Division of Main Line Therapy Solutions offers evaluation services for diagnostic, educational, and treatment planning purposes.  Our evaluators are school certified and have a doctorate in either Psychology or Neuropsychology.  All evaluations are completed in a warm and comfortable environment, and we have offices that are child-friendly to help provide a less stressful evaluation experience for the younger children. We can assess for learning disabilities, intellectual functioning and gifted qualification, attentional and executive functioning challenges, autism spectrum disorders, 504 accommodations (such as the need for extended time), and behavioral and/or social adjustment issues.  We also provide post-concussive assessments to determine an individual’s level of current functioning as they heal from a concussion.  Assessments typically require 1-3 meetings of 1.5-3 hours each.  Once the evaluation has been completed and a report generated, the evaluator will review the testing results in detail in order to explain findings, make recommendations, and provide families with an opportunity to ask any questions they might have. Results can also be reviewed with the assessed child/teen, if desired.  Though our assessments are not covered at an in-network rate by insurance, clients are encouraged to check with their insurance company to see if they have any out-of-network coverage for psychoeducational evaluations.  A superbill can be provided for such reimbursement, if needed.  In addition, we often have practicum students and interns who can provide evaluations at a reduced fee.  Such evaluations are supervised by a senior, licensed psychologist.    Please contact our office with any questions.
