From the website of the National Council for Curriculum and Assessment (NCCA):
What is a standardised test?
Standardised tests measure your child's achievement in literacy and numeracy compared to other children throughout the country at the same class level or age level. Schools are required to administer these tests at the end of second, fourth and sixth class
Scoil Ursula uses standardised tests every year from 2nd class up. In our school we inform parents of the test results using STen scores. Below you can find a useful information leaflet produced by the NCCA. Further information for parents on standardised testing, as well as translations of the leaflet in different languages can be found by clicking on this link.
