Effective January 1, 2014, the Indiana Department of Workforce Development switched to the new high school equivalency test developed by McGraw Hill called the Test Assessing Secondary Completion, or TASC. It is computer based, although a paper-based test is available. You'll see reference to PBT (paper-based test). The state formerly offered the GED (General Educational Development) test from GED Testing Service.
There isn't a lot of information about the new test on the Indiana site, but there are links to the TASC site, where you'll find lots of info.
Indiana does provide free programs to help adults learn math, reading, and writing, and you'll find links on the Indiana site to those services.
Good luck! Whatever you call the test, come back and share your experience with others: Which Part of the GED Test Is Easiest/Hardest?
