As a parent of a young child who is in an early intervention (EI) or early childhood special education (ECSE) program, you want to be sure these services are helping your child develop and learn. These services are designed to make the most of each child's potential, as well as to strengthen the family's ability to help their child. But how can you know if your child's early intervention or special education program is meeting his or her needs? One way to learn more about your young child's progress is through three "child outcomes" that are measured for every child in the United States who participates in an early intervention or early childhood special education program. These outcomes will help you know how well your child is developing and participating in activities at home, at school, or in the community. In addition to helping you measure your child's individual progress, these outcomes are also used to measure how well your child's early intervention or early childhood special education program is serving all children who are enrolled. By participating in the outcome process, you are not only helping your own child but are also helping your district and state know how early childhood programs are performing overall. As the parent, you are a critical part of your child's development and education, and this handout will help you understand and meaningfully participate in the outcome measurement process for your child's program.
