Iowa State Test practice sets

This Iowa State Test Practice page provides five short practice sets with 10 original multiple-choice questions each. The sets cover ISASP English Language Arts and reading, mathematics, science and data reasoning, reading and writing applied skills, and integrated Iowa review.

Iowa assessment overview

The Iowa Department of Education describes the Iowa Statewide Assessment of Student Progress (ISASP) as a summative accountability assessment aligned to Iowa Core academic standards. Current assessment information lists English Language Arts and mathematics in Grades 3–11 and science in Grades 5, 8, and 11 for the current 2026–27 direction. Assessment names, achievement levels, and grade details can change as Iowa updates its statewide summative assessment.

How to use this page

Complete one 10-question set at a time. Return to the passage, graph, table, model, or calculation, then review the explanation after each response.

This is supplemental State Test Practice, State Assessment Practice, and Standardized Test Practice. It does not replace current Iowa Department of Education guidance, official blueprints, accommodations, test tools, or testing procedures.

1. QuestionMultiple choice

Which variable should be kept constant when testing how light intensity affects plant growth?

Please select an answer first.

Correct answer: A

The correct answer is The type and age of the plants.

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: Keeping plant type and age constant helps isolate the effect of light intensity.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

Keeping plant type and age constant helps isolate the effect of light intensity.

2. QuestionMultiple choice

Which process transfers energy from sunlight into chemical energy stored in glucose?

Please select an answer first.

Correct answer: B

The correct answer is Photosynthesis.

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: Photosynthesis uses light energy to build glucose from carbon dioxide and water.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

Photosynthesis uses light energy to build glucose from carbon dioxide and water.

3. QuestionMultiple choice

Why are there usually fewer organisms at higher trophic levels?

Please select an answer first.

Correct answer: C

The correct answer is Less usable energy is transferred at each trophic level..

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: Energy is used for life processes and released as heat, so only part transfers upward.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

Energy is used for life processes and released as heat, so only part transfers upward.

4. QuestionMultiple choice

A cold front moves into an area. Which weather change is most likely?

Please select an answer first.

Correct answer: D

The correct answer is A drop in temperature as colder air advances.

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: A cold front occurs when colder air advances and can lower temperature.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

A cold front occurs when colder air advances and can lower temperature.

5. QuestionMultiple choice

Which evidence best supports the claim that two rock layers formed at different times?

Please select an answer first.

Correct answer: A

The correct answer is The layers contain fossils from different periods and are arranged in sequence..

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: Fossil succession and relative position provide evidence about the relative ages of rock layers.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

Fossil succession and relative position provide evidence about the relative ages of rock layers.

6. QuestionMultiple choice

What happens to matter during a chemical reaction in a closed system?

Please select an answer first.

Correct answer: B

The correct answer is Atoms are rearranged but not created or destroyed..

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: The law of conservation of matter states that atoms are rearranged during reactions.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

The law of conservation of matter states that atoms are rearranged during reactions.

7. QuestionMultiple choice

A force of 10 newtons pushes a box 3 meters in the same direction. How much work is done?

Please select an answer first.

Correct answer: C

The correct answer is 30 joules.

  1. Identify the Iowa task: Determine whether the question asks about reading, writing, mathematics, science, data, or evidence.
  2. Use the information provided: Work equals force times distance in the direction of the force: 10 × 3 = 30 joules.
  3. Check the response: Confirm that the answer matches the passage, model, data, calculation, or Iowa assessment skill.

Work equals force times distance in the direction of the force: 10 × 3 = 30 joules.

8. QuestionMultiple choice

A graph shows that a stream became clearer after a filter was installed. What conclusion is best supported?

Please select an answer first.

Correct answer: D

The correct answer is The filter may have reduced particles in the water..
