A child up to age seven who is experiencing a measurable delay in development according to diagnostic instruments and procedures fits the Developmental Delay (DD) disability category. Minnesota Rule information about DD can be found under offsite resource links.

The Minnesota Department of Education's Early Learning Services offers information and resources on DD through its Help Me Grow programs. For information on infant and toddler intervention services, preschool special education or information and referral through Help Me Grow, see the offsite resources links or call toll-free 1-866-693-4769. 

A teacher with an Early Childhood Special Education license is licensed for all areas of disability for children who are ages Birth to age 5. If a student qualifies under a categorical disability and is enrolled in Kindergarten or beyond, a teacher who is licensed in the student’s disability area is a required team member whenever the IEP team meets, and that team member must also participate in the student's evaluations.
