Original sentence: As a Field Auditor, auditors can receive commissions on people referred to Orgs and a 15% FSM commission on completed services.Courses, books and counseling are available for a "fixed donation".In 1995, Operation Clambake, a website critical of the Church, estimated the cost of reaching "OT IX readiness", one of the highest levels, is US $365,000 – $380,000.Scientific analysis has also proven that the test evaluation is "rigged", in that it is impossible to get a perfect score and that even completely randomized or deliberately contrary sets of answers tend to give almost exactly the same results.The churches and people performing the tests get a commission from any fees for future tests.The test "results" are used to tell the recipient that Scientology courses and "auditing" would "benefit" them
