Hi, Am a new head coming to middle of second term in charge. I have created an online questionnaire for parents to inform the SDP and was pleased with a 55% response rate. There are a few negative responses to each question, some with more than others. As a leader, at what percentage should I start to get worried? What do Ofsted consider is a significant number of complaints? e.g. 5%, 10%, 20% of responses Any advice would be great.
