# Correctness
Dolt is [99.99% compatible](https://docs.dolthub.com/sql-reference/benchmarks/correctness) with MySQL based on a
standard suite of correctness tests called `sqllogictest`.
-A similar comparison for Doltgres coming soon.
+We use these same tests to measure the correctness of DoltgreSQL.
+
+Here are DoltgreSQL's sqllogictest results for version `0.3.0`. Tests that
+did not run could not complete due to a timeout earlier in the run.
