This credential recognizes Direct Support Professionals who have demonstrated competence (measured and approved by the NADSP). This credential sets this group of DSPs apart from other DSPs in that they have demonstrated skills that typical entry level DSPs would not have acquired. The primary competence credential for direct support practice, the DSP-Certified credential is the core of our credentialing program. Regardless of specialization, every DSP approved as a DSP-Certified has demonstrated skills and knowledge that enable him or her to practice high quality direct support.
