National Developmental Disabilities Awareness Month – March 2025

National Developmental Disabilities Awareness Month (D.D.A.M.), observed throughout March, is a nationwide event to raise awareness about the inclusion of people with developmental disabilities and address the barriers that those with disabilities face. Inclusion is necessary since about 15% of the world’s population lives with a disability. D.D.A.M. is about understanding the relationship between the way people function and how they participate in society and making sure everybody has the same opportunities in every aspect of life to the best of their abilities. Find out why acceptance is a fundamental element of D.D.A.M. and what you can do to support this initiative.

History of National Developmental Disabilities Awareness Month

Back in the 1960s, people with intellectual and developmental disabilities (I.D.D.) were regarded as ‘mentally disabled,’ and often relegated to the back rooms of family homes or underfunded state-run institutions open to neglect and abuse.

In the early 1960s, President Kennedy leveraged his family’s personal experience with his sister Rosemary’s disability and used the power of the Presidency to bring attention to the needs of people experiencing life with an intellectual and developmental disability (I.D.D.). He convened a Presidential Panel focused on the exclusion from education, employment, and community participation suffered by people with I.D.D.

The D.D. Act of 1984 set up much of the system we all experience today. The emphasis on goals for services for people with developmental disabilities is “to achieve their maximum through increased independence, productivity, and integration into the community.” State Developmental Disabilities Councils were implemented in all states and territories. These were intended to provide additional training to individuals, families, and service delivery systems. They were to develop a statewide strategic plan for services over the next five years to build on community needs.

In 1987 President Reagan proclaimed March as National Developmental Disability Awareness Month to focus awareness on the potential of citizens with I.D.D. to work, contribute, and enjoy typical lives.

In 1990, another landmark year, President Bush signed the Americans with Disabilities Act (D.D.). The act was amended again to move from the goals of independence, integration, and productivity toward interdependence, inclusion, and recognition of individual contributions. Training opportunities were expanded to include professionals, paraprofessionals, family members, and individuals with developmental disabilities and advocate for innovative public policy and community acceptance.

The D.D. Act continues to grow to include affirmation of individual dignity, person-centered goals, and multicultural focus inclusive of individual and family participation.

5 Important Facts About Developmental Disabilities

  1. When does it begin?

    Most developmental disabilities begin before a baby is born, but some can happen after birth because of injury, infection, or other factors.

  2. What causes it?

    Most developmental disabilities are thought to be caused by a complex mix of factors including genetics, parental health and behaviors (such as smoking and drinking) during pregnancy, birth complications, infections, and exposure to high levels of environmental toxins, such as lead during pregnancy.

  3. Over one billion

    About 15% of the world's population live with a disability.

  4. The numbers are increasing substantially

    More and more people are living with disabilities due to demographic change including population aging and the global increase in chronic health conditions.

Why National Developmental Disabilities Awareness Month is Important

  1. It seeks to stop bullying and stereotypes

    Bullying of students with special needs has become a serious and growing national problem. Some reports indicate that nearly 85% of students with special needs experience bullying. Stereotypes about people with disabilities contribute to the prevailing high unemployment rate among people with disabilities.

  2. It fosters peer relationships

    D.D.A.M. is a time to create strategies and activities that help students better understand the needs and differences of their peers with disabilities. It helps to foster peer relationships and helps students develop empathy that can have positive outcomes for all students.

  3. It educates the community

    It is helpful to educate our community to be aware that developmental disabilities are not always evident. For example, some disabilities are visible — a person who uses a wheelchair or crutches to ambulate. Oher disabilities — cognitive challenges that affect the way a person speaks, learns, or interacts with others are not easily recognized or noticeable.
