Ensuring parents take responsibility for their children's education is important but local authorities and those in teaching jobs
should avoid alienating families.
A spokesperson for the Association of Teachers and Lecturers said that when enforcing parent-school agreements authorities should be careful not to "create a wedge between parents and schools".
Children whose parents are least-involved in their education do tend to perform worse, she added, but this should not contribute to a "blame culture".
Home School Agreements were originally introduced as part of the government's 21st Century Schools programme.
Under the agreements parents can be fined up to £100 if their child is missing school regularly, according to the Directgov website.
If a child is not enrolled at a local school and parents have not made suitable alternative arrangements then a school attendance order may also be issued.
Other aspects of the programme include encouraging schools to offer extended services offering parenting advice and support.
