Information about officially registered educational attainment from Statistics Norway was later obtained for the same participants, and information from both sources was compared for 344 participants.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>When dividing the participants into three educational groups, 77 % were classified in agreement with the officially registered educational attainment by self-report with regard to educational attainment. Twenty percent overreported their own educational attainment, while only 3% underreported. When dividing the participants into only two educational groups according to whether they had university\/college education or not, 86% were in agreement with the officially registered educational attainment, 12% overreported their educational attainment and 2% underreported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The majority of participants were classified in agreement with the officially registered educational attainment by self-report, but overreporting was more common than underreporting.
