The Association of Test Publishers (ATP) was founded to promote and develop testing and assessment best practices and to facilitate an environment that would benefit test-takers, businesses, educational organizations, and society in general. ATP charges itself with defining professionalism for assessment and ethics, and promoting adherence to these principles. To achieve this purpose, ATP focuses on two initiatives: advocacy for the industry and education for its members. The association is committed to promoting the benefits of best practices in testing and the value of these benefits to society.
