Introduction 1.1 Background Ipsos MORI has been commissioned by the Centre for Longitudinal Studies (CLS) to carry out the fifth sweep of the Millennium Cohort Study (MCS5). The MCS is a longitudinal cohort study of people born in the UK in 2000/1 and sweep 5 takes places when the children are 11 years old. Fieldwork for MCS5 will begin in 2012. This report documents the headline findings from the second (dress rehearsal) pilot for the fifth sweep of the Millennium Cohort Study (MCS5 pilot 2). This pilot was conducted between 25th August and 27th September 2011 in 13 locations in England, Scotland, Wales and Northern Ireland, and included all core elements that will be included in the main stage: Household grid CAPI questionnaire Main respondent CAPI and CASI questionnaires Partner CAPI and CASI questionnaires Child paper and audio self-completion questionnaire Child cognitive assessments Child physical measurements Cognitive observations Collection of cohort members’ teacher’s contact information Consents and assents Most of these elements had been provisionally tested in the first pilot study. However, this pilot was the first time that the audio support for child self completion questionnaire had been tested, and so this was a priority focus for the pilot testing. The pilot also tested the feasibility of a potential new element: collecting child contact details for the purpose of enabling communications to be sent directly to children in the future. Subsequent to the data collection above, a mixed-mode postal and telephone survey took place with the cohort member’s teachers. Details of the Teacher Survey appear in the Teacher Survey dress rehearsal report. 1.2 Pilot objectives The main objective of the dress rehearsal was to test the entire survey process, at a stage when the data collection instruments were almost finalised. The dress rehearsal was designed to replicate what will actually be happening in the main stage as closely as possible. The following specific areas were tested: Contact procedures and approaches to gaining co-operation and consent Procedures for tracing movers
