Referral Concerns

Poor planning, forgetfulness, difficulty managing time, or trouble shifting between tasks.

The Value of Assessment
What a Comprehensive Evaluation Can Clarify
An attention and executive function evaluation examines how a student regulates focus, manages tasks, and sustains effort—not just whether attention is inconsistent, but why and how it affects learning.
Whether attention or executive function difficulties are contributing to school or work challenges
The pattern of strengths and weaknesses across attention, memory, and processing
Whether classroom accommodations or support strategies are appropriate
How to communicate findings clearly to teachers, schools, and support teams
