Does the United States and the state of Colorado face a shortage of scientists and engineers?


The Colorado State Science Fair, Inc. honors excellence in science, technology, engineering and mathematics; providing opportunities for students from all regions of the state to create and present their research in environments that nurture interest in science and technology; promoting professional skills, high ethical standards, diversity and continuing intellectual development. Learn More about the history, goals & objectives and board of directors that oversees the CSEF.


Participation in a science fair can be a very rewarding experience. Students use the full range of science, technology, engineering and mathematical practices to make sense of natural phenomena and solve problems that require a deep understanding of their topic area. Learn More about the practices, crosscutting concepts and core ideas that participation in CSEF can teach students.

The CSEF is affiliated with the Intel International Science & Engineering Fair. For this reason, we must adhere to the international rules and guidelines set forth by the Society for Science & the Public's Scientific Review Committee. These rules outline the forms and supervision that are needed for all projects as well as those that involve human subjects, vertebrate animals, potentially hazardous biological agents and hazardous chemicals, devices and activities. Please remember that these rules are in place to ensure the safety of the student researcher as well as the subject (human or animal) that they may be working with in their student. They are NOT trivial and are based on what working scientists must adhere to as well as federal laws and regulations. Learn More about the forms required for participating in Colorado regional science fairs and the CSEF.

All students (with individual and team projects) who wish to participate in the 2019 Colorado Science & Engineering Fair must:

  • be a Colorado resident 6th-12th grade student in a public, private, parochial, home or on-line school and
  • participate in only one Regional Science Fair located in the county where they go to school (or live if home-schooled) and
  • be chosen by their Regional Science Fair to represent that region at the CSEF and
  • agree to abide by all International Science & Engineering Fair, CSEF and Regional Science Fair rules, regulations and policies that may currently exist regarding pre-college science research.

Registration is currently closed for the 2019 CSEF - check back in early February 2019. Learn More about the CSEF registration process.

We Need You!
Judging for the 2019 CSEF will be held Thursday, April 11th so mark your calendars now! Grand Award Judging is an all-day event and judges need to be in attendance at the CSEF from 10 a.m. - 5:30 p.m. Learn More about being a Grand Award Judge for the CSEF.

Registration for the 2019 CSEF is now OPEN!

Sponsored Special Awards supplement the Grand Awards given in each category and division. Organizations provide representatives to judge exhibits and present awards based on their criteria. Awards may include cash, savings bonds, calculators, scientific equipment and/or summer job opportunities. Learn More about the CSEF Special Awards Program.

The CSEF is run almost entirely by volunteers, from the Board of Directors who help guide policy of the event and organization to the judges who evaluate the students' research. The only way this event happens is through the wonderful people who volunteer their time to put it together. Learn More about becoming a CSEF Volunteer.

The Colorado State Science Fair, Inc. is an independent, nonprofit organization. Thanks to the support of generous corporations, foundations, government agencies, organizations and individual donors who believe in the importance of science education, the CSEF has been service Colorado and its students for 64 years. Learn More about our current sponsors and how you can also support us.
