 ====== Educational Attainment ======
-An educational attainment score (low, middle or high) of adult [[cohort|Lifelines]] participants was calculated based on their self-reported [[education|highest obtained degree]] in [[1A Questionnaire 1]] and [[2A Questionnaire 1]] (i.e. variables degree_highest_adu_q_1/_a or EDUCATION & EDUCOTHER) ([[sections|section]]: [[secondary & linked variables]]). The coding procedures are described below.
+An educational attainment score (educational_attainment_adu_c_1	or EA) of 'low', 'middle' or 'high' was calculated for all adult [[cohort|Lifelines]] participants who provided an answer to the [[education|highest obtained degree]] questions in [[1A Questionnaire 1]] and [[2A Questionnaire 1]] (i.e. variables degree_highest_adu_q_1/_a or EDUCATION & EDUCOTHER) ([[sections|section]]: [[secondary & linked variables]]).\\ The coding procedures are described below.
+The Educational Attainment variable can be requested in the [[https://data-catalogue.lifelines.nl/|Lifelines catalogue]].\\

+Addition 2026: a researcher compared the EA coding to the SOI2011 and ISCED2013 and concluded that they largely correspond but differences do exist (e.g. MBO2 has been coded low, while ISCED and SOI would code it middle).\\
