A guide has revealed Harrow 's top performing secondary schools.
The Real Schools Guide 2018 has been designed to offer a much fuller picture of education than standard league tables.
Put together by Reach's data unit, the guide takes into account more than 50 different factors, including GCSE results, attainment and progress scores as well as absence rates and pupil-to-teacher ratios.
According to the guide Bentley Wood, in Clamp Hill, came an impressive 203rd when ranked out of 3,088 secondary schools in the country.
Meanwhile Hatch End High School, in Headstone Lane, was Harrow's school with the lowest score, ranking 1,066th compared to all other schools in the UK which are included in the guide.
The survey features all non-private secondary schools in the borough and ranked them on the basis of a specially designed and weighted 50 data-point system.
The Real School Guide scored eight of Harrow's secondary schools so parents don't need to look any further for a definitive ranking of secondary schools in the borough:
Here is how The Real School's Guide collated their information:
The unique rating system uses 50 different measures, put together from the latest publicly-available data and broken into four categories - attainment, progress, attendance, and outcomes.
National league tables may only look at overall GCSE results, as well as newer measures.
Attainment
This is worth 30 per cent of the total score. It is based on pupils' average grade attainment score, including what the average scores for different groups of pupils were, as well as the proportions gaining the English Baccalaureate and those getting A* to C grades in GCSE subjects. It measures whether a school is getting top marks, and if it is managing to improve year-on-year.
Progress
This is worth 40 per cent of the score. It is based on how well different types of pupil do in terms of progressing. It also looks at things that may contribute to teaching outcomes, such as how big the pupil/teacher ratio is in comparison to the national average, as well as teachers' average salaries.
Attendance
This score is based on absence rates, looking at both overall levels of sessions missed as well as unauthorised and persistent absence at the school. It is worth 15 per cent of the total score.
Outcomes
This is also worth 15 per cent, and is based on what proportion of pupils continue with education after Year 11 or go on to training and work.
Schools that had no Year 11 pupils taking GCSEs in 2017 are not rated.
