Children with intellectual disabilities are one of Cambodia's most abused and rejected populations. Hagar's Community Based Rehabilitation (CBR) program addresses these needs.

Hagar currently operates four integrated classrooms in three government schools as well as its original House of Smiles care centre in Phnom Penh.  A Hagar staff member works at each government school location, providing children with education, independent living skills, physiotherapy, aids to support their mobility and support for their parents.  Parents are encouraged to assist with the classes and are offered a small stipend and training in return for the time they give. 

Hagar's CBR model raises awareness of disability in Cambodia and encourages the inclusion of children with disabilities in society. The integrated classroom is located on school property, encouraging children with and without disabilities to play and get to know each other. The CBR model also drastically reduces costs as facilities are provided by the government and only one staff member is needed at each location.

Hagar continues to run its residential facility, House of Smiles. House of Smiles provides a home and specialized services for a small number of children who have been orphaned or abandoned by their families.
