National curriculum assessments: optional key stage 1 tests

Guidance for headteachers, teachers and test administrators involved in administering the optional national curriculum tests at the end of key stage 1 (KS1).

National curriculum tests at the end of KS1 are optional and available in: 

  • English reading 
  • English grammar, punctuation and spelling 
  • mathematics 

They are developed to the same specifications as previous KS1 papers, to support schools in the measurement of pupil achievement and to help identify where their pupils need additional support as they transition into key stage 2. The tests may also provide helpful information when reporting to parents, although there is no requirement for schools to do so.  

We recommend that schools administer the tests in May. Schools can: 

  • order hard copies of modified versions of the tests from the National Curriculum Assessments Portal (NCA Portal) between October and November, for delivery in April 
  • access standard and modified large print versions of the test papers and mark schemes securely online, on the NCA Portal, throughout May 
  • access materials in the GOV.UK collection of past test materials from June onwards, after the recommended administration period, when they are publicly available  

Schools can use the information on this page to check important dates for the optional KS1 tests and find guidance on administering them, including details on the format, recommended equipment and assistance for each test.

While the end of KS1 tests are optional, the following remain statutory:
