Races is a sequential memory subtest (i.e. in which items have to be remembered in the correct order). It correlates significantly with later literacy development. The correlation of Races given at age 5 with BAS Word Reading at 6:6 was 0.50, with Macmillan Individual Reading Analysis (MIRA) at 6:6 was 0.58, with Edinburgh Reading Test at 8:0 was 0.52, and with BAS Spelling at 8:0 was 0.53. All were significant at the p<0.01 level. For further information on the statistical evidence see Singleton, Thomas and Leedale (1996) and Singleton, Thomas and Horne (2000).
