Hi, I am new to this bulletin board and was very happy to see this particular forum. I work in an Early Intervention program for infants and toddlers with developmental delays, and am also the parent of a young person with significant cognitive disability. I notice on a couple posts a mention of "certification". Is this through the Developmental Disabilities Nursing Assoc (not sure I have the correct title, actually)? Or some other certification process? I would really appreciate an explanation of how you were certified and by what agency/organization, and if you feel it helped your career or found it otherwise worthwhile. Thanks.
