Accuracy and reliability

Overall accuracy

The reliability of the educational information is considered to be high. The information in The Student Register is obtained from the institutions' administrative register and goes through a comprehensive error check in connection with the annual data collections. The update of The Student Register further requires that the active students are rediscovered each year. Thus, there must be continuity in reporting over the years. The uncertainty arising from the fact, that the institutions through the annual reports have the opportunity to correct and report data backwards in time are notoriously approximately 0-3pct. The uncertainty is particularly true over the last year.

Quality management

Statistics Denmark follows the recommendations on organisation and management of quality given in the Code of Practice for European Statistics (CoP) and the implementation guidelines given in the Quality Assurance Framework of the European Statistical System (QAF). A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.

Quality assurance

Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.

Quality assessment

The reliability of the educational information is judged to be good. The information in The Student Register is obtained from the institutions' administrative register and goes through a comprehensive error check in connection with the annual data collections. The update of The Student Registry further requires that the active students are rediscovered each year. Thus, there must be continuity in reporting over the years. The uncertainty arising from the fact, that the institutions through the annual reports have the opportunity to correct and report data backwards in time are notoriously approximately 0-3pct. On more specific groupings and individual training security will be higher. The uncertainty is particularly true over the last year.

There is a memo on Statistic Denmark's homepage describing important aspects of this year's data collection to The Student Register Paper on Education

Data revision - policy

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.

Data revision practice

The figures from the latest year could be considered provisional because of the possibility of updating backwards in time when the institution is reporting. When updating Statbank Denmark with the present year, the previous year is also updated.
