Independent Educational Evaluation (IEE)
A school district is required by law to conduct assessment for students who may be eligible for special education. If the parent disagrees with the results of a school district’s evaluation conducted on their child, they have the right to request an independent educational evaluation. The district must provide the parent with information about how to obtain an IEE.

Individualized Education Program (IEP)
Special education term used by IDEA to define the written document that states goals, objectives and services for students receiving special education.  An IEP for a deaf child should take into consideration such factors as:
- Communication needs and the child's and family's preferred mode of communication
- Linguistic needs
- Severity of hearing loss and potential for maximizing auditory ability
- Academic level
- Social and emotional needs, including opportunities for peer interactions and communication.

Individualized Education Program Team
Term used to describe the committee of parents, teachers, administrators and school personnel that provides services to the student. The committee may also include medical professionals and other relevant parties. The team reviews assessment results and determines goals, objectives and program placement for the child needing services.

Individualized Family Service Plan (IFSP)
A process of providing early intervention services for children ages birth to 3 with special needs. Family-based needs are identified and a written plan is developed and reviewed periodically.  According to IDEA an IFSP should address:
- Assessment of the child's strengths and needs, and identification of services to meet such needs.
- Assessment of family resources and priorities, and the identification of supports and services necessary to enhance the capacity of the family to meet the developmental needs of the infant or toddler with a disability.
- A written individualized family service plan developed by three members of a multidisciplinary team including the parent or guardian

Interim Alternative Educational Setting (IAES)
A setting other than the student’s current placement that enables the student to continue to receive educational services according to his or her IEP. The IAES must enable the student to continue to participate in the general education curriculum, although in another setting, and progress toward meeting the goals set out in the IEP. Students in an IAES should also receive, as appropriate, a functional behavioral assessment, behavioral intervention services and modifications that are designed to address the behavior violation so that it does not happen again. The particular IAES is determined by the student’s IEP team.

Interpreter or Transliterator for the Deaf:
