Britain's self-styled 'strictest head teacher', whose non-selective West London academy saw 98 per cent of its students achieve 4+ (C) or more in last week's GCSEs, says teachers across the UK can get similar results if they follow her advice.
Michaela Community School head Katherine Birbalsingh, who tweets prolifically as @Miss_Snuffy on Twitter, has seen exam results continue to soar, and puts the school's success down to high expectations in a disciplined environment.
This week, she shared advice with teachers heading back to the classroom after the summer break, suggesting that early nights, learning to laugh with pupils and 'sweating the small stuff' on messing around could transform any school's fortunes.
