The GQII is based on publicly available data. The research team collects and selects the data.
The GQII uses data from the following sources:
- The Key Comparison Data Base of the International Bureau of Weights and Measures (BIPM) (qi4d post for more details)
- The ISO Survey on Quality Management Standards and the Data on Technical Committies of the International Organization for Standardization (ISO). (qi4d post for more details)
- Data from national accreditation bodies that are members of the International Laboratory Accreditation Cooperation (ILAC) and the International Accreditation Forum (IAF). (qi4d post for more details)

Due to the heterogeneity of the database, a significant task is to clean up the data and make the data comparable.
