Each student took two of the three tests so as to provide comparative information between tests but without overloading students. The numbers of students in each year-group taking each test is therefore roughly two-thirds of the total number of students involved in that age group.","identifier":"10.5255/UKDA-SN-851382","creator":[{"@type":"Person","name":"Hodgen, J","affiliation":{"@type":"Organization","name":"King"}},{"@type":"Organization","name":"Coe, R, Durham University"}],"temporalCoverage":"2008-04-01/2012-09-30","spatialCoverage":"United Kingdom","datePublished":"2014-09-05","dateModified":"2024-07-15"}
