The Value of Specialty Certification


For Nurses:

To be certified means that you are competent in your chosen field and have a recognized level of achievement. You understand and comply with the standards of your professional organization, live by those standards professionally, and set an example of excellence. Certification attests to your knowledge in your chosen specialty area of nursing practice. Certification provides a way to demonstrate your experience, competence, and proficiency beyond that required for nursing licensure. As a nurse practicing in the field of developmental disabilities, certification also documents that you possess special knowledge and gives you access to expanded career opportunities and advancement. As a certified nurse, you also benefit the profession of nursing, the specialty of developmental disabilities, and the people for whom you care.

For Employers:

When you hire an RN or LPN/LVN who is certified in IDD nursing, you can be assured that the certified nurse has experience in working with persons with IDD, has demonstrated a high degree of expertise in the field of IDD nursing, and maintains that level of expertise by completing ongoing continuing education specific to the field of IDD nursing. Clients generally leave programs or facilities for one of four reasons: dissatisfaction with services, needs that exceed program capabilities, decline in health, or death. By having a certified nurse on staff, you can increase your clients’ satisfaction with services, meet their complex nursing care needs, and help to ensure their health and quality of life. Having a CDDN or DDC makes the difference!
