Parents Asked For Views On Schools
Almost half of Scots parents believe schools' parent councils should be involved in raising attainment among pupils, a survey has found.
The majority of parents - 71% - strongly agree that it is important for schools and parents to work together, the online questionnaire found.
The survey was undertaken by the Scottish Parliament's Information Centre, on behalf of the Education Committee as part of its work on attainment.
It ran from January 14 to March 5 and received a total of 2,599 responses.
It asked questions about communication with schools, involvement with the parent-teacher council and sought ideas on how schools and parents might work together.
The majority (56%) of parents completing the survey were from Edinburgh, with 22% of those responding having children in independent schools.
It found that around a third of respondents with children in state schools are actively involved in a parent council compared with only 6% of independent school parents.
Almost half of state school parents think the parent council should help improve attainment (47% agree or agree strongly), while a significant minority are neutral on the issue (31%) and over a fifth disagree or disagree strongly (22%).
Committee convener Stewart Maxwell said: "Parents and guardians play a crucial role in their children's education and we wanted to hear from them about the part they play in their child's education.
"Whilst this is clearly an Edinburgh-centric sample, it paints an important picture about the need for schools and parents to work closer together in order that children can achieve their very best at school. This is something we can all agree is desirable.
"The survey also reveals that those with children in independent schools find it easier to get information about how their child is progressing than those in state schools.
"Our committee will explore whether there are lessons to be learned about keeping parents informed.''
