&lt;b&gt;Secure Access Dataset:&lt;/b&gt;&lt;br&gt;
The &lt;I&gt;Understanding Society: Linked National Pupil Database: Secure Access&lt;/I&gt; study contains nine files extracted from the &lt;I&gt;National Pupil Database&lt;/I&gt; (NPD). These can be linked (within the Secure Access service) to &lt;I&gt;Understanding Society&lt;/I&gt; participants using the cross-wave personal identifier (variable pidp). The NPD files include information on pupil background, attainment, school absences and exclusions for all individuals with a valid consent to education linkage collected in Wave 1 of &lt;I&gt;Understanding Society&lt;/I&gt;. This includes consents collected from parents of children aged 4-15 and of young adults aged 16+ and born in 1981 or later. The included files cover Pupil Level Annual School Census (PLASC) data on pupil background; pupil attainment data for the Early Years Foundation Stage Profile (EYFSP) (age 5) and Key Stages (KS) 1 (age 7), KS2 (age 11), KS3 (age 14), KS4 (age 16) and KS5 (ages 17-18); and absences and exclusions (ages 4-16). See documentation for further details.&lt;br&gt;

The Secure Access version of &lt;I&gt;Understanding Society&lt;/I&gt; is held under SN 6676. This  has more restrictive access conditions than standard End User Licence or Special Licence Access versions; further details and links to the less restrictive versions can be found on the &lt;a href="http://discover.ukdataservice.ac.uk/series/?sn=2000053" title="Understanding Society series"&gt;Understanding Society series Key data&lt;/a&gt; webpage.&lt;br&gt;
&lt;br&gt;
The Archive also holds separate (i.e. not linked to &lt;I&gt;Understanding Society&lt;/I&gt;) data from the &lt;I&gt;National Pupil Database&lt;/I&gt;, available under Secure Access and Safe Room Access conditions. See SNs 7626, 7627 and 7628 (Secure Access) and SNs 7590, 7625, 7600, 7595, 7612 and 7606 (Safe Room Access) for details.&lt;br&gt;

The second edition (December 2015) includes data files for absences, exclusions and Key Stage 5, as well as an updated documentation file.&lt;br&gt;

 &lt;p&gt;&lt;i&gt;Understanding Society&lt;/i&gt; (UK Household Longitudinal Study), which began in 2009, is conducted by the Institute for Social and Economic Research (ISER), at the University of Essex, and the survey research organisations are Kantar Public and NatCen. It builds on and incorporates, the British Household Panel Survey (BHPS), which began in 1991. The latest release combines the first seven waves of Understanding Society data with harmonised data from all eighteen waves of the BHPS. As multi-topic studies, the purpose of Understanding Society and BHPS is to understand short- and long-term effects of social and economic change in the UK at the household and individual levels. The study has a strong emphasis on domains of family and social ties, employment, education, financial resources, and health.&lt;br&gt;
&lt;br&gt;
&lt;i&gt;Understanding Society&lt;/i&gt; is an annual survey of each adult member of a nationally representative sample. The same individuals are re-interviewed in each wave approximately 12 months apart. When individuals move they are followed within the UK and anyone joining their households are also interviewed as long as they are living with them. The study has five sample components: the general population sample, a boost sample of ethnic minority group members, an immigrant and ethnic minority boost sample (from wave 6), participants from the BHPS and the Innovation Panel (which is a separate standalone survey (see SN 6849 for EUL version; SN 7083 for Special Licence version; and SN 7332 for Secure Access version). The fieldwork period is for 24 months. Data collection primarily uses computer assisted personal interviewing (CAPI), but includes a telephone mop up, and from Wave 7 of Understanding Society, web-based interviews. One person completes the household questionnaire. Each person aged 16 or older participates in the individual adult interview and self-completed questionnaire. Youths aged 10 to 15 are asked to respond to a paper self-completion questionnaire. For the general and BHPS samples biomarker, genetic and epigenetic data are also available (see SN 7251).&lt;br&gt;
