Approval of CompaniesITF Recognition Assessor logo

A court owner or product supplier may engage a company other than an ITF Accredited laboratory to conduct testing to obtain One-Star ITF Recognition.

Prior to commencing work, any such company must seek approval from the ITF by providing the following information in English:

- Confirmation that the company possesses equipment with the required accuracy to conduct the tests for evenness, slope and planarity, and dimensions.

- Information on company accreditation to a national or internationally recognised quality management system, or other relevant qualifications (e.g. membership of professional bodies).

- Evidence that the company has the knowledge and capability to conduct the on-site tests. A reference list of tennis courts tested in the preceding two years may be supplied in this regard. If the company has no prior experience of testing tennis courts, the company will be requested to conduct all One-Star tests on a minimum of two (local) courts, and complete an ITF report, which it will send to the ITF to review.

- Details of any work undertaken for National or International Governing Bodies of Sport, Sports Associations, Councils or Federations.

The information must be submitted on an ITF form which is available on request by email to Upon obtaining ITF approval, the surveying company will be listed on this website.
