Several certification programs exist to support the professional aspirations of software testers and quality assurance specialists. No certification now offered actually requires the applicant to show their ability to test software. No certification is based on a widely accepted body of knowledge. This has led some to declare that the testing field is not ready for certification. Certification itself cannot measure an individual's productivity, their skill, or practical knowledge, and cannot guarantee their competence, or professionalism as a tester.
What four traits can a certification not measure?
individual's productivity, their skill, or practical knowledge

In 1977, two thirds of the Presbyterian Church of Australia, along with most of the Congregational Union of Australia and all the Methodist Church of Australasia, combined to form the Uniting Church in Australia. The third who did not unite had various reasons for so acting, often cultural attachment but often conservative theological or social views. The permission for the ordination of women given in 1974 was rescinded in 1991 without affecting the two or three existing woman ministers. The approval of women elders given in the 1960s has been rescinded in all states except New South Wales, which has the largest membership. The theology of the church is now generally conservative and Reformed. A number of small Presbyterian denominations have arisen since the 1950s through migration or schism.
The approval of women elders which was given in 1960 has been rescinded in all of the Australian states except one, which state did not?
