It wasn’t for the school, the plans were offered at the state level. Every teacher had 2 options, 3 if you were there long enough to get the plan with the lower $4K deductible. Otherwise, you could get a plan with a $6K deductible with a $500 premium.

When I left, I found a plan with a deductible below $1K with a ~$300 premium through the same insurance provider.
