One of the most daunting tasks for meet hosts is to secure officials. A common strategy is to use officials certified by USA Swimming or other swimming organizations, but sometimes that is not sufficient. USMS has now started its own certification program; please see this page for more details.
There are currently two certification levels: Stroke and Turn Official, and Starter. Note that USMS certification is NOT required for officials currently certified by USA Swimming, NCAA, NFHS, or the YMCA.
