Calculators are to be banned from maths tests for 11-year-olds amid concerns that primary school students are overly reliant on them, the Department for Education said.
Pupils will be prevented from using calculators in the maths national curriculum tests from 2014.
The tests, known as Sats, are split into three papers and pupils are allowed to use calculators in one 45-minute exam. Sats are taken by youngsters in their final year of primary school.
Education minister Elizabeth Truss said: "By banning calculators in the maths test, we will reduce the dependency on them in the classroom for the most basic sums".
