The Rock Trust Housing First project supports care leavers aged 16- 25 who are homeless or at risk of becoming homeless in West Lothian. The Housing First for Youth (HF4Y) project operated as a 31-month pilot, starting in September 2017. It aimed to offer access to appropriate independent housing, provided through Almond Housing Association and West Lothian Council, alongside intensive, on-going support from project workers. This evaluation was commissioned and funded by the Housing First Europe Hub. It was undertaken by Imogen Blood & Associates, with the University of York.
