Credit Scores — Credit Glossary Hub

There is no single credit score. Lenders pull different scoring models for different decisions, and the score you see on Credit Karma or Experian rarely matches the score a mortgage underwriter sees. The terms below cover both the consumer-facing scores (FICO 8, VantageScore 3) and the FICO Classic mortgage suite (FICO 2/4/5) lenders actually use.

This hub gathers every term in the Credit1Solutions glossary that falls under the Scores category. 33 terms appear below in alphabetical order, each with a plain-English definition you can cite when reviewing a credit report, drafting a dispute letter, or comparing what a lender, bureau, or attorney is telling you about your file.

The vocabulary here is the same vocabulary our attorney network uses when investigating FCRA accuracy claims, FDCPA collection-conduct claims, and ECOA discrimination claims. We refresh definitions as case law evolves — most recently for the 2022 CFPB medical-debt rule, the post-Spokeo standing requirements for FCRA litigation, and the 2023 NIST guidance on synthetic-identity fraud.

If a term you are looking for is not in this hub, check one of the eight sibling hubs below or the master glossary index. Every term in the Credit1Solutions glossary is reachable from one of the nine category hubs.
