The PPRSEF is an ISEF affiliated science fair.  All projects must meet the requirements set up by The International Science and Engineering Fair (ISEF), a program of Society for Science & the Public (SSP), the world’s largest international pre-college science competition. The complete guidebook of 2021 rules and guidelines can be found at:

Display and Safety rules for the 2020 PPRSEF can be found here:  Display & Safety Regulations PPRSEF - 2020.pdf   These will be updated for the 2021 Fair.

Student registraion for the 2021 PPRSEF will be open from August 20, 2020 through January 20, 2021.

The PPRSEF is open to all 6th - 12th grade students in any educational setting (public, charter, private or home school) in Elbert, El Paso, Park or Teller County.  Projects may be entered by individuals or teams of 2 or 3 students.  

Students are required to have projects approved by the PPRSEF SRC or a school SRC before experimentation begins.  Please check with us at  if you have questions.

** Original, completed ISEF forms should be kept in a project folder and be available on the day of the fair. 



The Pikes Peak Regional Science Fair, Incorporated (PPRSF) is a non-profit corporation dedicated to stimulat­ing and encouraging youthful interest in science and sci­entific endeavors through student participation in regional, state, and international science fairs. The Pikes Peak Re­gional Science and Engineering Fair serves students in grades 6 through 12 in all school districts (including private schools, parochial schools, and home schools) in Elbert, Teller, Park, and El Paso Counties.  There is no requirement for students to participate in a school or area fair to enter the PPRSEF.


2021 will mark the 64th annual Pikes Peak Regional Science Fair.  Additional facts about the PPRSF may be found ou the 2021 PPRSEF Fact Sheet. 2021 PPRSEF Fact Sheet.pdf

Please note - our plan is to have students judged virtually at least two times in the morning or afternoon judging rounds.  It is expected that students be available for the full day.   We will email more specific directions for judging times in the week before the fair,


The 2020 Pikes Peak Regional Science and Engineering Fair was held on Saturday, February 22, 2020, at UCCS.

The Awards Presentation was held on Tuesday, February 25th, in Armstrong Hall at Colorado College; 14 E Cache la Poudre St.

For students in grades 4 and 5, the Pikes Peak Elementary Science and Engineering Fair is usually held in April at Mitchell High School. The 2020 PPRSEF has been cancelled.  The fair is for students in grades 4 and 5 who place at their school science fairs in the categories of Biology, Physical, Health and Behavioral, Consumer Science or Engineering Design.  Interested participants can contact Darian Founds at for more information or visit the website: 

Public Display

Only PPRSEF Board members, judges and registered volunteers are allowed in the virtual exhibition rooms.  

We plan to provide public access to the Digital Project Displays from Sunday, February 21st - Wednesday, Feb 24th.

The Awards Presentation is still in the planning stages!


What to Expect the Day of the Fair

Students should dress nicely, but comfortably, for the virtual juding rounds.   Students will not be judged continuously, but we hope to be able to send out a range of judging times in the week leading up to the fair.  Until specific schedules are established, students should plan to be avaiable for virtual judging between 9:00 AM and 3:00 PM on Saturday, February 20, 2021

Special Awards judges will be judging the digital diplays beginning February 17, 2021.  These judges will not conduct in person interviews.

Details about Awards Announcements is still being formuated.
