The International Headache Society expressly permits translations of all or parts of ICHD-3 (beta) for purposes of field testing and/or education, but will not endorse them. Endorsements may be given by member national societies; where these exist, such endorsement should be sought. All translations are required to be registered with the International Headache Society. Before embarking upon translation, prospective translators are advised to enquire whether a translation exists already. All translators should be aware of the need to use rigorous translation protocols. Publications reporting studies making use of translations of all or any part of ICHD-3 (beta) should include a brief description of the translation process, including the identities of the translators (of whom there should always be more than one).
