Every year we perform a survey of certifications to our management system standards. The survey shows the number of valid certificates to ISO management standards (such as ISO 9001 and ISO 14001) reported for each country, each year.

ISO does not perform certification. Organizations looking to get certified to an ISO standard must contact an independent certification body. The ISO Survey counts the number of certificates issued by certification bodies that have been accredited by members of the International Accreditation Forum (IAF).

ISO Survey 2015

A total of 1,519,952 certificates were issued worldwide in 2015, compared to 1,476,504 the previous year, an increase of 3 %.

This year we added a new management system standard, ISO/IEC 20000-1:2011 Information technology – Service management – Part 1 Service management system requirements, after recommendations from international accreditation and certification experts that we consult annually. This brings the total of standards surveyed to 9.

Despite our best efforts to display consistent results, there are fluctuations in the number of certificates from year to year due to:

  • The variability in numbers of certificates reported each year by individual certification bodies
  • Inconsistent participation of some certification bodies that contribute to the survey one year but not the next
  • The participation of new certification bodies
