  1. Key issues from yesterday and for panel Lorraine Dearden

  2. Dearden • School League tables here to stay in England • But very difficult to measure the value added by schools • Given not likely to go away, we need to do it better • To inform parent choice • To make schools accountable

  3. Marsh et. al. • Variation of outcomes explained by schools/universities not great • Variation in outcomes explained by teachers within schools/universities where focus should be (like US) • Should focus more on teachers who make much more of a difference for educational outcomes • Wider measures of outcomes

  4. Cunha • Can think of measuring school effectiveness in way you think about skill accumulation over the life-cycle • Really important to think of implications of measurement error and sampling error • Important to remember that academic outcomes are not the only important measure of school effectiveness • Transparency is probably bad...

  5. Leckie and Goldstein • School league tables ignore the uncertainty in using current performance as a guide to future performance • Adjusting for this uncertainty reduces the number of schools that can be separated to almost none • The way you should measure school effectiveness for parents and schools accountability different

  6. Vignoles, Micklewright and Dearden • Schools are differentially effective across the prior ability distribution • Having average school measures of effectiveness may not be useful • parents need to know the value added by a school for children with similar prior attainment to their own child • These measure needs to be transparent and simple • Rankings of school vary quite widely if look within different prior ability groups

  7. Brown and Tzavidis • Use M-quantile approaches to estimate ‘robust’ CVA models • Measures how well a child does relative to children with same inputs and prior ability (cf typical regression approaches) • If rank LAs using this efficiency measure in London get very different story to using standard CVA regression approach

  8. Smith • There are many dimensions to measuring school effectiveness • Mixture of • Regulation • Professionalism • Markets • Performance management (teacher work force data) • Hard to do well and we are doing alright... • The perfect and the good: friends or enemies

  9. Key issues • Measuring school effectiveness very hard • Easy to critisize CVA models, but the fact that the government has adopted a CVA model and gives researchers access to NPD should not be under-estimated • Remember Jeff’s wise words!!! We have incredibly rich vein of research in the UK using these data and we have learned much...

  10. Where does research need to go? • Teacher effects in the UK data but we cannot ignore schools. How big is the school effect? • Making full use of teacher work force data which links teachers to schools and has some info on characteristics (out this summer) • Modelling parent preferences • Local information, statistical information • How actual decisions are made?

  11. Where does research need to go? • Measurement error • Validation with external sources • Sampling error • Need better information on who applies to schools? • Stability over time? Significant differences between schools? • Are all schools really equally as effective when projecting forward 6 years? Or is it just we cannot be certain? • Pooling data?

  12. Where does research need to go? • Has UK research underestimated the importance of strategic responses by agents? • How serious is the problem? This one for more research • how do teachers/schools game? • How do parents game? • study curriculum choices etc?

  13. Where does public policy go? • Clearer recognition we have two sets of data or measures that we need • Measure for accountability (of schools? Of teachers?) • Measures for parents (simple is an issue!) • Maybe approach for each is different • Recognition it is a mix of • Regulation • Professionalism • Markets • Performance management (teacher work force data)

  14. Where does public policy go? • Transparent? Not transparent? • Gaming the system. • Maybe not transparent for accountability but transparent for parents? • If gaming is at KS2 is that a problem? • If the outcome measure is outside school control is it a problem?

  15. Where does public policy go? • Wider set of outcomes • Non cognitive? • HE participation? • Behaviour e.g. Crime, exclusions • Safety (this is something parents care about) • Multiple measures to minimise gaming • But if measures are within school (not externally validated) is this a problem?

  16. Leave this to the panel discussion..
