Within the UK, every Home-Start program undertakes self-assessment of its practice according to national quality assurance standards and criteria. The self-assessments are validated during a quality assurance review with Home-Start UK every three years. One-third of all local Home-Start programs are reviewed each year, including interviews with families, volunteers, trustees, and staff. Each local Home-Start collects monitoring and evaluation information about the support of families and Home-Start UK collects information annually from local programs on the needs of families and on Home-Start’s response to those needs. Local Home-Starts endorsed by the Charity Commission for England and Wales may also undergo an enhanced quality assurance review to assess compliance with additional endorsement requirements.
