DE - Trends in International Mathematics and Science (TIMSS) 2023

TIMSS has been conducted every four years since 1995. Northern Ireland has participated since TIMSS 2011 and TIMSS 2023 will be the fourth cycle of TIMSS Northern Ireland will have participated in. For the 2023 cycle TIMSS will transition to the electronic based assessment version of the study, eTIMSS. The student contextual questionnaire will also be delivered electronically which was initiated in TIMSS 2019. Tenderers should be aware of and reflect the methodology set out by the study organisers the IEA (see Annexes 1 and 2) and approved by the Department, in their tenders. Tenderers should pay particular attention to: • Sampling methodology; • School and pupil participation rates; • Pupil assessment mode; • Contextual questionnaires mode(s); and • Study administration procedures. For each of the above referenced aspects of the delivery of TIMSS 2023, tenderers should note that the NRC will be responsible for ensuring that the requirements of the IEA, as the study organisers, are met.
