Accuracy and reliability

Overall accuracy

The reliability of the educational information is judged to be good. The information in The Student Register, comes from the institutions' administrative register and goes through an comprehensive error check in connection with the annual data collections. The update of The Student Registry further requires that the active students are rediscovers 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 bag in time are notoriously approximately 0-3 pct. The uncertainty is particularly true over the last year.

The census of children in basic schools and upper secondary schools covers all pupils in all schools approved by the Ministry of Education, and the statistics covers practically all children in Denmark. Few records is deleted, if the civil registration number can not be established. The few number of children, who are not enrolled in a school, as they receive home education are not part of the basic school statistics. Fore this reason the number of children receiving education in Denmark is slightly underestimated.

Students, who choose to be enrolled in further education abroad will be placed in the category Have no records of further education, as Statistics Denmark is not receiving information of education from other countries.

Sampling error

Not relevant for these statistics.

Non-sampling error

The statistics covers almost every child in Denmark. The lack of complete coverage can be caused by an error in a schools data report. Children who for varies reasons are not enrolled in a school is not covered in the statistics. However children who is does not have a civil registration number, but is attending classes in a Danish school is covered by the statistics. Children recently migrated to Denmark is in that category - e.g. children seeking asylum or children of expats. Moreover children living in another country but goes to school in Denmark (eg. the Danish minority in Germany or children of diplomats) are also covered by the statistics. By comparison with the Civil registry the number of children in this statistic is higher.

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.

On more specific groupings and individual training security will be higher. The uncertainty is particularly true over the last year.

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

Only final statistics are published.
