We lead the nation in setting the gold standard for Independent Educational Evaluations (IEEs), combining clinical precision with clarity that drives confident, informed decision-making.
Through our work, we bridge families, schools, and legal systems—delivering unbiased insight that protects educational rights, promotes equity, and helps every learner thrive.
We clarify. We uphold. We transform special education.
At Cognitive Diagnostic Associates (CDA), we set the national standard for independent educational evaluations. Our work is guided by the following core principles:
Every student is unique. We are committed to tailoring our evaluations to reflect each individual’s strengths, challenges, and needs. Our team uses a comprehensive, student-centered approach to ensure that evaluations are meaningful, accurate, and actionable.
We serve as independent evaluators. Our role is to provide clear, evidence-based insights rooted in clinical best practices. We remain neutral and objective in every evaluation, offering findings that can stand up in both educational and legal settings.
Education and clinical practice evolve. Our team remains at the forefront by engaging in ongoing professional development, research, and cross-disciplinary collaboration. We leverage the most current tools, technologies, and methodologies to deliver best-in-class evaluations.
We believe that when parents, educators, and districts receive clear, well-supported findings, they are better equipped to make informed decisions that support students’ educational outcomes.
We are active contributors to the communities we serve. Through professional collaboration, educational initiatives, and outreach, we work to improve systems-level understanding of diverse learners and promote better access to quality assessments.
CDA fosters an environment of mutual respect, open communication, and professional growth. We recognize the strengths of every team member — from clinical staff to administrative leaders — and cultivate a collaborative culture that drives quality and innovation.
We honor the backgrounds, languages, traditions, and experiences of the students and families we serve. Culturally responsive evaluation is essential to accuracy, and we incorporate this lens into every step of our assessment process.
