Analysis (Insight) Intelligence NCER - Content Editor 20 September 2019 09:26 Updated The school intelligence page shows you an overview, and detail, of significance testing applied to your school attainment and absence data. Significance testing is done to determine whether your value for an indicator is a strength, a challenge or within normal bounds. Printing & Help If you're reading this guide, you probably don't need to click about this page, but if you do, you'll find some basic information about the page you are viewing. We've also included a link to this guide. If you want to print the page, you can, but consider whether the person you're printing for should have access to Analysis (Insight), or whether you could screenshot the parts you want. Options Ac. Year... You can choose the academic year you want to look at, there will be a maximum of 3 academic years at any given time. Dimension... The default dimension is All Dimensions, each indicator will be considered for significance for each of the 3 available dimensions when this is selected. Select Gap to National if you are only concerned with how the school has performed against the national cohort. School Summary The top of this page shows a summary of the significance testing performed on your school. You are tested for significance in 3 ways... Gap to National Year on Year Trend Rank Trend As we see in the below screenshot, absence has 12 possible points of significance, there are 4 absence indicators, and each is tested for 3 dimensions. Areas Click on an area in the overview section to jump to the corresponding area on the page. Strengths and challenges show in 2 columns, each indicator is tested for significance and the result will be displayed. The school in the example below is significant because their RWM expected standard has increased from 51.9% in 2017/18 to 59.9% in 2018/19.

Significance Testing Methodology Significance testing is done to determine whether a school's value for an indicator is a strength, a challenge or within normal bounds. Significance testing for KS2 progress is done at pupil level, all other indicators are school level. School-level 5-sigma Confidence Interval Significance Test NatStdDev = The national standard deviation of school-level indicator values. NatAvg = The national average of school-level indicator values. Coh = The number of eigible pupils in the focus domain (e.g. school). CI = The 5-sigma confidence interval for the indicator of the focus domain. Val = The indicator value of the focus domain being tested. CI = 5 * (NatStdDev / SQRT(Coh)) Sig+ if Val - CI > NatAvg Sig- if Val + CI < NatAvg ...else, not significant Pupil-level 95% Confidence Interval Significance Test NatStdDev = The national standard deviation of pupil-level indicator values. NatAvg = The national average of pupil-level indicator values. Coh = The number of eigible pupils in the focus domain (e.g. school). CI = The 95% confidence interval for the indicator of the focus domain. Val = The indicator value of the focus domain being tested. CI = 1.96 * (NatStdDev / SQRT(Coh)) Sig+ if Val - CI > NatAvg Sig- if Val + CI < NatAvg ...else, not significant Related articles How to Log In
