Shifting AI Adoption Patterns: The proportion of teachers who have never used AI for schoolwork has fallen to under 10%. Primary teachers initially led adoption for generating exemplars and short-form questions, while maths teachers have seen a major turnaround since tools gained image and diagram generation capabilities. Environmental and Ethical Concerns: Environmental impact has emerged as a primary reason why the remaining minority of teachers choose to abstain from using AI tools in their professional duties. Anonymity Drives Honest Reporting: True data separation and absolute respondent anonymity are vital for understanding shadow AI usage and unearthing candid feedback that school policies might otherwise mask. Designing Actionable School Surveys: When surveying staff, school leaders should restrict questions to recent, specific timeframes (such as "this week"), keep options below ten, and eliminate unnecessary verbiage to obtain clear, reliable responses.
