A preferred criteria matrix is an underwriting reference tool that summarizes a carrier's preferred and super preferred guidelines in a grid format, listing allowable ranges for build, blood pressure, cholesterol, family history, driving record, and other risk factors. The matrix shows which combinations of factors qualify for preferred classes and which fall to standard or substandard. It helps underwriters and field partners quickly evaluate whether a case is likely to meet a desired rate class. Because each carrier's appetite and experience differ, preferred criteria matrices are unique and may be updated periodically as mortality data and competitive pressures evolve. Using the matrix correctly helps align expectations between producers and underwriting and reduces surprises when final offers are issued.

In practice, wholesalers and case designers rely on preferred criteria matrices when prescreening cases and choosing which carrier to quote. They may share cleaned-up versions of the matrix with producers so they can field underwrite more accurately. During training sessions, agencies often walk advisors through sample matrices to highlight differences between carriers, such as stricter cholesterol limits or more lenient build tables. When an offer comes back worse than expected, case managers may revisit the matrix to confirm whether all risk factors were properly disclosed. Over time, familiarity with preferred criteria matrices improves placement ratios and allows advisors to give more realistic premium estimates up front.
