Early intervention is full of terms that people constantly use in writing and in conversation, and it’s important to know what those terms mean. We are pleased to provide this handy reference to early intervention terminology, and hopes it helps our readers quickly connect with the meaning of pivotal words and phrases in the field.

Point of Reference: Part C of IDEA
It’s extremely important to understand that many of the terms you’re likely to hear in early intervention come from our nation’s law authorizing this program for infants and toddlers with disabilities, Part C of IDEA (Individuals with Disabilities Education Act). You’ll find many, many references to this law on the CPIR’s website and in its publications, because IDEA guides how early intervention (Part C) and special education and related services (Part B) are provided to children with disabilities in the United States, birth to age 21.
States develop their own policies and procedures based on what IDEA requires. States are allowed to go beyond what IDEA requires–and frequently do, because the law leaves a great many things to State and local discretion. However, States are not permitted to have policies or procedures that are not consistent with IDEA’s provisions.
This being the case, the starting point of early intervention terms and what they mean is always how Part C of IDEA defines the terms (most of which are provided through this page and elsewhere on this site). Your State’s definition of a term is then important to consider, because it will influence how the term is being used in your area, especially if the State definition isn’t exactly the same as IDEA’s.

The Part C regulations define consent at §303.7, as follows:
Consent means that—
(a) The parent has been fully informed of all information relevant to the activity for which consent is sought, in the parent’s native language, as defined in §303.25;
(b) The parent understands and agrees in writing to the carrying out of the activity for which the parent’s consent is sought, and the consent form describes that activity and lists the early intervention records (if any) that will be released and to whom they will be released; and
(c)(1) The parent understands that the granting of consent is voluntary on the part of the parent and may be revoked at any time.
(2) If a parent revokes consent, that revocation is not retroactive (i.e., it does not apply to an action that occurred before the consent was revoked).
Additional provisions of import | The following provisions are also important with respect to parental consent.
§303.420 Parental consent and ability to decline services.
(a) The lead agency must ensure parental consent is obtained before—
(1) Administering screening procedures under §303.320 that are used to determine whether a child is suspected of having a disability;
(2) All evaluations and assessments of a child are conducted under §303.321;
(3) Early intervention services are provided to the child under this part;
(4) Public benefits or insurance or private insurance is used if such consent is required under §303.520; and
(5) Disclosure of personally identifiable information consistent with §303.414.
(b) If a parent does not give consent under paragraph (a)(1), (a)(2), or (a)(3) of this section, the lead agency must make reasonable efforts to ensure that the parent—
(1) Is fully aware of the nature of the evaluation and assessment of the child or early intervention services that would be available; and
(2) Understands that the child will not be able to receive the evaluation, assessment, or early intervention service unless consent is given.
(c) The lead agency may not use the due process hearing procedures under this part or Part B of the Act to challenge a parent’s refusal to provide any consent that is required under paragraph (a) of this section.
(d) The parents of an infant or toddler with a disability—
(1) Determine whether they, their infant or toddler with a disability, or other family members will accept or decline any early intervention service under this part at any time, in accordance with State law; and
(2) May decline a service after first accepting it, without jeopardizing other early intervention services under this part.

The definition of developmental delay in the Part C regulations of IDEA is actually very tiny. Here it is:
§ 303.10 Developmental delay.
Developmental delay, when used with respect to a child residing in a State, has the meaning given that term by the State under §303.111.
As can be seen, the entirety of the term is defined by each State, for use with children residing in that State. This gives enormous flexibility to each State—within the parameters of what specific other provisions in the Part C regulations require–especially the following:
§303.111 State definition of developmental delay.
Each system must include the State’s rigorous definition of developmental delay, consistent with §§303.10 and 303.203(c), that will be used by the State in carrying out programs under Part C of the Act in order to appropriately identify infants and toddlers with disabilities who are in need of services under Part C of the Act. The definition must—
(a) Describe, for each of the areas listed in §303.21(a)(1), the evaluation and assessment procedures, consistent with §303.321, that will be used to measure a child’s development; and
(b) Specify the level of developmental delay in functioning or other comparable criteria that constitute a developmental delay in one or more of the developmental areas identified in §303.21(a)(1).
Editor’s note | The developmental areas mentioned in the above definition are:
- Cognitive development
- Physical development, including vision and hearing
- Communication development
- Social or emotional development
- Adaptive development

Early intervention services are to be provided in natural environments to the maximum extent appropriate for the child and for the service being provided. Here’s Part C’s definition of the term.
§303.26 Natural environments.
Natural environments means settings that are natural or typical for a same-aged infant or toddler without a disability, may include the home or community settings, and must be consistent with the provisions of §303.126.
And what might the provisions of §303.126 have to say?
§303.126 Early intervention services in natural environments.
Each system must include policies and procedures to ensure, consistent with §§303.13(a)(8) (early intervention services), 303.26 (natural environments), and 303.344(d)(1)(ii) (content of an IFSP), that early intervention services for infants and toddlers with disabilities are provided—

Service Coordination Services
And last but not least, here’s how the Part C regulations define the term service coordination services, which is referenced in the definition of early intervention services above.
§303.34 Service coordination services (case management).
(a) General. (1) As used in this part, service coordination services mean services provided by a service coordinator to assist and enable an infant or toddler with a disability and the child’s family to receive the services and rights, including procedural safeguards, required under this part.

(ii) Coordinating the other services identified in the IFSP under §303.344(e) that are needed by, or are being provided to, the infant or toddler with a disability and that child’s family.
(b) Specific service coordination services. Service coordination services include—
