Scenario

A sociology student called Hannah wants to investigate whether parental involvement has an impact on educational achievement. She is interested in questions such as how often parents help with homework, attend parents’ evenings, check revision, communicate with teachers, encourage reading, and talk to their children about school. Rather than carrying out long interviews, Hannah decides to use self-completion questionnaires given to a large number of parents and carers across several schools.

Hannah thinks questionnaires will allow her to collect information from many people in a relatively short amount of time. She plans to include mostly closed questions, such as how often parents help with homework, whether they attend school events, and how confident they feel contacting teachers. She may also include a few open questions so parents can explain barriers to involvement, such as work patterns, transport, language issues or previous negative experiences with schools. Because the questionnaire can be completed privately, Hannah hopes some parents will feel more comfortable answering honestly than they might in a face-to-face interview.

There are clear strengths to this method. Self-completion questionnaires are relatively cheap, practical and capable of reaching a large sample. Hannah can compare answers more easily because many respondents will be answering the same questions in the same format. This may help her identify patterns, such as whether more frequent parental contact with school is linked to stronger student performance. The anonymity of the questionnaire may also reduce embarrassment for some parents, especially if they feel unsure about admitting that they rarely help with homework or do not often attend school events.

However, there are also limitations. Some parents may ignore the questionnaire altogether, leading to a low response rate. Others may misunderstand questions or interpret terms like “help with homework” or “involvement” in different ways. Parents may also give socially desirable answers, overstating how often they support their child because they want to appear responsible and committed. Since questionnaires usually produce brief answers, they may miss the deeper meanings behind parental behaviour. For example, a parent who rarely attends school events may still care deeply about education but face practical barriers such as work, childcare or anxiety about school settings.

From a sociological point of view, Hannah’s study highlights both the strengths and limitations of using self-completion questionnaires to investigate parental involvement in educational achievement. The method can produce useful quantitative data, identify broad patterns and make comparison easier across a larger sample. At the same time, it may have limits in validity, depth and response rates. This means questionnaires can be useful for showing trends, but may need to be combined with interviews or case studies to understand parental involvement more fully.
