## Definition

a standard or rule you use to judge or decide something. You use it to see if something is good enough or fits a specific need.

For teachers: a standard, rule, or principle by which something is judged or a decision is made. Often used in academic or professional contexts to evaluate performance or eligibility.

## Examples

- The main criterion for the job is previous experience.
- Academic success is not the only criterion the university uses to select new students for the program.
- While cost remains a significant criterion in the procurement process, the committee must also weigh environmental impact and long-term sustainability when selecting a primary supplier.

## Pitfalls

- Not "This is the main criteria." but "This is the main criterion." — Learners often use the plural 'criteria' when they are referring to a single standard.

## Usage notes

- The word is the singular form; the plural form is 'criteria'.
