Q. How do I Harvard reference the 2007 phonics programme Letters and Sounds?

Download the original Letters and Sounds booklet from this webpage. The booklet can be referenced as follows:

Department for Education and Skills (2007) Letters and sounds: principles and practice of high quality phonics. Available at: https://assets.publishing.service.gov.uk/media/5a7aa7b6e5274a34770e630c/Letters_and_Sounds_-_DFES-00281-2007.pdf (Accessed: 27 February 2025).

For information, here is a Government blog post about the removal of Letters and Sounds from the list of validated programmes:
