What is a Developmental Disabilities Associate Certification?
The Developmental Disabilities Associate Certification is a professional credential designed for direct support professionals (DSPs), paraprofessionals, and care workers who provide essential assistance to individuals with developmental disabilities. It certifies foundational knowledge in caregiving practices, communication techniques, ethical responsibilities, and safety protocols specific to the I/DD population.

The goal is to standardize the quality of support and empower workers with tools to advocate for and assist their clients more effectively.

Should I retake practice tests?
