Looking way ahead, it seems that there may be a change to the way the Warwickshire exam is scored for 2014 (for places in 2015 - current year 4 children).

From next year, it is understood that all three consortia will join together with one CEM examination on the same date. This is most likely to be the first Saturday in September.
If this is the case it means that same exam will be used for Warwickshire as for the the selective schools in Birmingham and Walsall. It will still be a CEM exam, and the format of the exam itself isn't likely to change, but the way it is scored might do. Currently Birmingham results are standardised to get two scores on English/VR and NVR/Numerical, whereas Warwickshire and Walsall have three elements with English/VR, NVR and Numerical being scored seperately. If Warwickshire adopts the Birmingham model it will shift the emphasis even more towards candidates who are strong in English as that will then account for half of the standardised score, rather than one third as it is now.
Good news if you've got a child who excels at English, not so good if they're more mathematically inclined.
