We use the Salford reading tests, which give a reading-age score for each pupil. This can then be compard to their chronological age. http://www.hoddertests.co.uk/tfsearch/ks1/reading/ssrtnew.htm We use the old version of the tests, which are really dry and uninspiring to read. It's purely summative in that, at the end of a period of time, it gives a "weighing the pig" sort of result. The results could be used formatively, if the person administering the test picked up, for example, that some children seem to be "missing" one grapheme or phoneme, and that then fed into planning. However, in my school the test is done by the TAs, and the results are only used to fill plastic wallets in ever-growing assessment files. Standardised tests are either the end of Key Stage SATS or optional SATS for the years in between. Reading is tested via a written outcome (!) : children read some information / a story etc and then answer questions on it, by providing written responses. Results are then able to give age-standardised scores. Hope this helps a bit!
