# test (assessment)

a change that occurs in a place during time to compare a thing with a regular pattern

- Computed level: L10 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: test

## Emergence
**Emerges from:** [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [event](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-event.occurrence), [compare](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-compare.relation), [regular](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-regular.frequency), [occurs](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-occurs.event), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension)

**Through:** When a change occurs and a compare with a regular pattern is made, a result follows.

**Novel properties:**
- temporal-spatial comparison
- deviation from repetition
- structured evaluation

## Examples
- The SAT assesses U.S. high school students annually to standardize college readiness. *(education)*
- The Hubble Space Telescope's calibration checks use known star brightnesses to detect instrument drift. *(astronomy)*
- New York City's 2010 soda portion cap was a policy test of public health intervention effects. *(governance)*
