Criteria

A model qualifies when one certification meets every value in at least one row.

Where the thresholds fall

Every model's representative certification on each rating Xcel CC checks, with its thresholds drawn. A model must clear every line of one path at once, on one certification, so these single-rating views show each hurdle, not the combined pass rate.
