Affiliate disclosure

Last updated: October 19, 2026

As an Amazon Associate I earn from qualifying purchases. NJ Civil Service Navigator earns money in two ways: display advertising, and commissions on some of the study guides, test prep and career services it links to. If you buy through one of those links, the site may earn a commission. The price you pay is the same as it would be if you had gone to the seller directly.

Display advertising

Pages carry ads served by Google AdSense, labeled “Advertisement”, including ads Google places automatically. Advertisers do not choose which pages we write or what those pages say. We do not put ad units of our own on error pages, search-results screens or pages with too little content to stand on their own. The privacy policy explains the cookies ads use.

Affiliate programs we use

• As an Amazon Associate I earn from qualifying purchases. Amazon (Amazon Associates): exam prep books. Amazon sets its own cookies so it can credit the referral, typically for 24 hours. See Amazon’s privacy notice.

Every page with an affiliate link carries a disclosure above the first link, in normal body text, never collapsed behind a click. Affiliate links are marked rel="sponsored" for search engines.

Where the links appear, and where they never do

Exam prep only shows up where it could help someone: on competitive-division job titles, which New Jersey fills by open competitive examination, and on the exam and hiring guides. You will not see exam prep on a non-competitive, unclassified or Senior Executive Service title. Those jobs are not filled by examination, so recommending study material there would be dishonest. The rule is enforced in the code that builds the site.

What we will not do

• We do not recommend a product because it pays more. Commission rates are not visible to the part of the site that decides what to show you.
• We do not claim any product is official. No study guide, course or practice test is published, endorsed or approved by the New Jersey Civil Service Commission, and none gives you an advantage in an examination.
• We do not show prices, ratings or reviews copied from a seller, because those go stale. Check the current price on the seller’s page.
• Nobody pays to appear in our editorial content, and no seller reviews it before it goes up.

Law enforcement exams need a specific warning

New Jersey tests entry-level law enforcement candidates with the Law Enforcement Examination, built on the LEAB, a cognitive aptitude battery. It is not the older memorization-heavy municipal police test most mainstream police exam books were written for. Two parts of the battery, the work styles questionnaire and the life experience survey, cannot be studied for, and we say so rather than sell you something that implies otherwise.

Independence and corrections

NJ Civil Service Navigator is an independent publication. It is not affiliated with, endorsed by, or an official resource of the State of New Jersey or the New Jersey Civil Service Commission. If something we link is a poor recommendation, out of print or wrong for the title it appears on, write to feedback@gavinrozzi.com and we will pull it. See also the editorial standards.
