EEI MASS Practice Test (2026) - Free Questions and Study Guide

Most utility companies enforce a waiting period of 30-90 days between attempts and limit candidates to 2 attempts within a 12-month period, though exact policies vary by employer. Entergy, for example, enforces a strict 30-day waiting period with a 2-attempt annual limit. Check directly with your employer's HR department for their specific retake policy before scheduling.

There is no universal passing score for the MASS test. Each utility sets its own cutoff independently, and most employers report results simply as "Recommended" or "Not Recommended" rather than sharing the exact index number - so in most cases you will be told whether you passed, not what you scored. The MASS is graded on an index of 0-15, with higher scores reflecting a stronger predicted likelihood of success in the role.

On score transfers: yes, it is possible in some cases. Several utilities - including Entergy (jobs.entergy.com) and Arkansas Electric (aecc.com) - allow candidates to submit a completed EEI Authorization to Release form to have a previous score transferred from another company, avoiding the need to retest. This is handled directly between the two employers, and is not guaranteed - if the previous score cannot be confirmed within a set timeframe, the new employer may still require you to test.

Both of these factors reinforce the same point: since you will not know your exact score, and since a passing result at one company may not meet the cutoff at another, your best position is always the highest score possible on your first attempt.

No, but they are closely related. Both are EEI pre-employment assessments for power plant roles and share some sections - Mechanical Concepts, Mathematical Usage, and Reading Comprehension. The key difference is the fourth section: the MASS uses Assembling Objects (for maintenance roles), while the POSS uses Figural Reasoning (for plant operators). Some utilities administer both tests together in a single session. You can find official test information at eei.org.

The MASS test is a proctored, paper-and-pencil assessment. It is not available online. It is administered directly by the hiring utility or at an approved third-party testing center, depending on the employer. Candidates are typically invited to test after an initial application review. For location and scheduling details, contact the HR department of the utility you are applying to.

The MASS test is a timed, section-by-section assessment - and time pressure is where most candidates struggle. The Mathematical Usage section gives you just 7 minutes to answer 18 questions, roughly 23 seconds per question. Each section is administered separately with its own clock, meaning you cannot borrow unused time from Reading Comprehension to offset a slow start in Mechanics. A static PDF can familiarize you with question types, but it cannot replicate this pressure. Preparing with a timed simulation - one that mirrors the actual section structure, question format, and per-section time limits - is the only way to train your pacing before the real test. JobTestPrep's MASS PrepPack is built specifically for this: full-length timed practice tests, section-by-section performance tracking, and detailed answer explanations so you understand not just what you got wrong, but why.
