Fourth Class

Ireland is one of 47 countries that participated in TIMSS at Fourth grade (Fourth class) in 2015. Ireland also participated at Fourth class, but not at Second Year, the last time TIMSS was held in 2011.

In Ireland, the next TIMSS Main Study will be carried out in spring 2019.In spring 2018, the TIMSS Field Trial) was carried out in a nationally representative sample of randomly-selected primary schools. The purpose of the field trial was to try out new test and questionnaire material in all participating countries in advance of the main data collection.

In smaller schools that are selected to participate, all Fourth class pupils are asked to take part in the assessment. In schools with three or more Fourth class groups, two of the classes are randomly selected (at the ERC) to participate. Testing will take place between March 25th and April 12th, 2019. Each pupil is asked to complete a test booklet containing maths and science questions.

Following completion of the test (and a break), pupils are given a short Pupil Questionnaire which asks some questions about the pupil, what they think about school, and, in particular, what they think about maths and science.  Information such as this is valuable in interpreting the results of the assessment, and in providing a snapshot of pupils’ views on their educational experience.

TIMSS also aims to gather useful information from other sources in order to build up a better picture of the Irish education system.  Therefore, teachers of selected classes are asked to complete a Teacher Questionnaire, and the school principal receives a School Questionnaire.  Parents of participating pupils are asked to complete a short Home Questionnaire about themselves and their child.

The initial results of TIMSS 2015 were published on November 29th, 2016, with additional contextual reports published in 2017 and 2018.
