GISP-E case studies
GISP-E · Put your knowledge to work in context.
The PreGISP® (GISP-E) Exam is offered under the GIS Certification Institute (GISCI), a nonprofit 501(c)6 organization incorporated in 2002 that also administers the international GISP (Certified GIS Professional) certification program. In GISCI's own framing, the PreGISP exam is a stepping stone towards becoming a certified GIS professional: it signals to employers that a student is serious about becoming a professional, and for employers it serves as a nationally acclaimed yardstick to compare job applicants. The GISP-E case studies are 5 cases and about 3,510 words.
