Tier 1 support is the first point of contact for a customer reaching out for help, typically handling common, well-documented issues using scripts, macros, and the knowledge base rather than deep technical investigation. If a Tier 1 agent can't resolve an issue within their scope, it escalates to Tier 2.

‍

‍Why it matters

Routing every inquiry straight to a senior specialist would waste their time on questions that already have a known, repeatable answer, and it would slow down the majority of customers whose issues are actually simple. Tier 1 exists to absorb that high-volume, lower-complexity work quickly, which only works well if the criteria for escalating to Tier 2 are clear enough that agents aren't guessing.

‍What good Tier 1 performance actually looks like

A low escalation rate on its own isn't the right target, since escalating a genuinely complex issue quickly is good practice, not a failure. The more useful signal is a low rate of unnecessary escalations, cases that could have been resolved at Tier 1 with better training or a clearer knowledge base article. Teams track this by having Tier 2 flag tickets that should have stayed at Tier 1, which feeds back into training and guideline updates.
