Selection route

  • Buckinghamshire Secondary Transfer Test

    Formal consortium · GL Assessment · Two Transfer Test papers: one assesses verbal skills and one assesses mathematics and non-verbal skills. A separate Practice Test is scheduled for 8 September. Buckinghamshire state-funded primary and Partner school pupils sit at school; other pupils are usually allocated a grammar school or another central test venue.

    GL marks the papers and scores are age-standardised. The total is weighted 50% verbal, 25% mathematical and 25% non-verbal; a total of 121 or more qualifies. A higher score gives no extra admission priority.
