Question
Which tests and items have calculators available, and what are the available calculators?

## What types of on-screen calculators are available?

As of October 2018, MAP Growth tests use the Desmos four function and scientific calculators. You can see how these calculators work at the   Desmos website, or in the MAP Growth practice tests. See   Practice tests (formerly test warm-ups) for MAP Growth.

## Can I practice using the calculators?

Yes. There are calculator practice tests for math and science. You can also practice using the calculators on the   Desmos website. See   Practice tests (formerly test warm-ups) for MAP Growth.

## Which tests use which calculators?

The four function calculator appears on items that are appropriate for calculator use on the MAP Growth 2-5, 6+, and high school math assessments. The scientific calculator appears on appropriate items on the MAP Growth 6+ assessments and the high school math assessments. These are the only test-level restrictions on calculators. No MAP Growth K-2 items or tests contain a calculator.

## Does NWEA use a graphing calculator on any test items?

Previously, NWEA had an advanced calculator that included graphing capabilities. However, this calculator has been phased out of MAP tests, and there are no current items in any MAP tests that require a graphing calculator.

## How does the test determine which calculator to display? Is it based on grade?

Aside from the above test restrictions, the individual items, and not the test itself, determine which calculator is available for use. Each item with a calculator has a specific calculator type. Students cannot choose a specific calculator. If an item includes a calculator, it is designed for use with that calculator type. The attached calculator should match the content and expected calculations for an item.

The MAP Growth test is grade agnostic, and therefore the calculator is not introduced at any particular grade level. They are assigned at the item level for appropriate items.

## Why don't all test items involving computation have a calculator available?

Many test items involving computation are specifically assessing a student's ability to perform a computation or make an estimate without the use of a calculator. The availability of a calculator is part of an item's difficulty, meaning that an item without a calculator will likely have a higher calibrated RIT score than a similar item with a calculator. Providing a calculator for an item that was calibrated without the use of a calculator would give the student an unfair advantage.
