The impact of the Covid-19 pandemic on children’s socio-emotional wellbeing and attainment during the Reception Year

The use of the ONS statistical data in this work does not imply the endorsement of the ONS in relation to the interpretation or analysis of the statistical data. [...] The main limitations are a consequence of the fact that this study’s data collection plan had to change as result of the disruption to schools in the 2020 autumn term and third lockdown which resulted in the termination of the national collection of the EYFSP. [...] A data sharing agreement was put in place between the University of York, the National Institute of Economic and Social Research (NIESR), the Education Policy Institute (EPI), and each school, which includes the details of the types of personal data being shared, the purpose and duration of that sharing, and the responsibilities each party has in relation to that information. [...] Sample size Because of the exploratory nature of this study and the short lead time into recruitment and data collection, the sample size was not determined to make sure the analysis achieved a certain power but rather depended on what the team deemed feasible given the timescale and the budget of the project. [...] The total number of parameters estimated in the model is three: (a) the fixed effect of the intercept, (b) the variance of the residuals, and (c) the variance of the intercepts.
