PIRLS and TIMSS
PIRLS is an international comparison study of reading achievement at ages 9-10 and TIMSS is a parallel study of mathematics and science at ages 9-10 (and ages 13-14, although Northern Ireland participated only at the younger age range). PIRLS has a five-yearly cycle and TIMSS a four-yearly cycle. 2011 was the first year in which the cycles of the two studies coincided, allowing the opportunity to assess the same pupils at ages 9-10 in all three subject domains. Northern Ireland took part in PIRLS and TIMSS for the first time in the 2011 cycle.
