Disclaimer: Use Third-Party Materials with Caution
Some test preparation materials available online—including those generated by artificial intelligence—may contain inaccuracies, outdated information, or misleading explanations. We recommend cross-checking any third-party content, especially AI-generated content found on Amazon with trusted sources and official test guidelines to ensure accuracy and reliability.
GISCI does not endorse any particular preparation materials, but we have placed some materials available here.
The Exam is fairly robust, and individuals cannot expect to do well with only a few hours of study. The Exam covers an extensive array of knowledge, fully described in the Exam Candidate Manual, and not all individuals will have come in contact with this during the course of their academic work or experience. However, the questions do come from those Knowledge Areas commonly encountered by active GISPs, and it is this minimal level of knowledge that a prospective GISP is expected to demonstrate in order to be approved for GISP Certification.
The most important document to start with for preparing for the exam is the Exam Blueprint. This contains the 45 KSAs from which every question on the exam comes.
Beginning with the June 2027 Exam, GISCI will use the 2026 Exam Blueprint. The December 2026 Exam will use the current blueprint.
