About the TASC Exam

Not having your high school diploma can seriously affect your future earning potential. Last year, the average wage for a person with a high school diploma was $35,000 per year, compared to only $25,000 for a person without one. That amounts to over $500,000 less earnings during a your entire career!

A high school diploma or its equivalent is also necessary for acceptance to college so getting your diploma will help you earn more and get ahead. If you left high school without graduating and your high school class has graduated, you are probably eligible to take either the TASC (if you live in New York) or the GED (if you live in New Jersey).

The TASC (Test Assessing Secondary Completion) consists of five subtests that are taken and scored individually:

5 star review

"The fundamentals I learned from Dr. Donnelly were very helpful. I received the one-on-one attention that I did not receive in the Kaplan prep test. I did not feel embarrassed to ask basic questions. Dr. Donnelly was very patient with explaining concepts in detail until I understood. Additionally, he was always available via email or phone."

5 star review

"Dr. Donnelly is a wonderful teacher. He is quick to pinpoint weaknesses and, in many cases, turn them into strengths. He always has a structured lesson plan and pertinent homework assignments and puts aside time in the lesson to go over "trouble problems" from the previous lesson. I highly recommend taking a prep course with him. His patience, humor, and kindheartedness makes an otherwise uncomfortable standardized test almost enjoyable."

TASC Overview

Exam Format and Structure


The TASC Exam

The TASC (Test Assessing Secondary Completion) consists of five subtests that are taken and scored individually:

The highest possible score in each subtest is 800, plus a score of 8 for the Writing essay. The passing score for each of these subtests is 500 and 2 for the essay. The cumulative TASC passing score is 2500 but you must still earn a passing score in every subtest to pass the TASC.

If you earn an especially high score in Mathematics, Reading, or Writing, you will receive a Distinguished Achievement notation for that score. The Distinguished Achievement score is 580 for reading and 560 for Mathematics and Writing.

You can retake a TASC subtest as many times as needed until you pass and you only need to retake those subtests that you failed rather than the entire TASC test. Similarly, if you do not pass in a particular area of the subtest, you need to retake only that area.
