ACT Online Testing
Set-Up and Technical Requirements
Optimal Testing Experience
For an optimal online testing experience, avoid testing on any computer that takes 10 seconds or more to start and run applications.
Determining Testing Capacity
To determine if your test site has enough computers to test all your examinees, use the formula below.
[number of devices] x [number of days you plan to test in the window] = examinee capacity
Note: For State and District testing, there are 6 days available in the online testing window.
TestNav and PearsonAccessnext
TestNav™ is the test delivery engine used by examinees to take the tests. PearsonAccessnext ™ is the web application used by testing staff to manage participation, ordering of materials, and online testing.
See the table below for minimum hardware requirements for devices used for testing.
