What is LRSEF?

The Louisville Regional Science and Engineering Fair is an annual science and engineering fair held in Louisville, Kentucky. Students in grades 6-12 from 52 Kentucky counties may enter the fair.

In addition to winning trophies, cash and other awards, top Junior winners are nominated to enter the national Broadcom MASTERS competition. Top Senior winners win a trip to compete in the International Science and Engineering Fair.

The mission of the Louisville Regional Science & Engineering Fair (LRSEF) is to awaken, promote, and recognize science and engineering talent among our area’s youth and act as a catalyst to promote science and engineering throughout Kentucky.


Students in grades 6 through 12 may register for the annual LRSEF as a result of being selected as a winning project at their school or county science fairs.  IF NO locally accessible fair is held, any student in public, private or home school may register directly for LRSEF with the support of their teachers.

Community Involvement

The LRSEF board is a group of adult volunteers with a deep passion and interest in science, technology, engineering and mathematics (STEM). The board mobilizes over 250 volunteers each year to engage in efforts to reward and recognize Kentucky student excellence and achievement in the STEM fields. Volunteers from many STEM careers serve as judges on fair day by interviewing and giving feedback to every student on their work.  Others serve as mentors for students throughout the year.

Volunteers conduct outreach activities to encourage teachers, principals and parents to get students involved. They also help recognize students and teachers by telling their stories through interviews and photography on LRSEF media. LRSEF volunteers solicit incentives for all students who enter the fair, and they seek additional funds to award winning projects.

On fair day, volunteers review all student projects for safety and compliance with ISEF standards. They assist students in registering and setting up their projects. Behind the scenes, volunteers tally results turned in by judges and prepare awards for distribution. They also plan and host an awards ceremony, which is open to parents and friends of all participants.


All participating students receive certificates, t-shirts and backpacks. Winning projects are awarded with ribbons, trophies and cash awards. Many STEM-related professional organizations sponsor Special Awards, including cash, medals, certificates, and other special prizes. On fair day, lunch is provided for all participants along with free admission for students and their families to the Kentucky Science Center.

The top three schools in both the Junior (grades 6-8) and Senior (grades 9-12) levels receive trophies and cash awards to highlight STEM achievement within the school community.

LRSEF sends the nominated winning projects and two leadership teachers to the Kentucky Science & Engineering Fair. The top 10 percent of students in the Junior division receive invitations to enter their projects in the Broadcom MASTERS national competition with a chance to win a trip to Washington, D.C.

LRSEF honors the Best of Fair Senior level winning projects with travel awards to attend the week-long International Science and Engineering Fair in May each year with two teachers and a chaperone. Funds also pay for substitute teachers.

Louisville Regional Science & Engineering Fair has been affiliated with the Society for Science and the Public since 1964. Society for Science and the Public Affiliated fairs are members of the (SSP) network. Competitions exist in nearly every state in the USA and in over 70 other countries, regions and territories. To compete in the annual International Science & Engineering Fair (ISEF), a student in grades 9 through 12 must first qualify by participating in a science and engineering fair that is affiliated with the ISEF. That fair sends a designated number of projects (individual or team) to the ISEF. Fairs are conducted at local, regional, and state levels from January through March. US Students in these fairs must observe the International Rules for Pre-College Science Research.

Broadcom MASTERS LogoFairs affiliated with Broadcom MASTERS (Math, Applied Science, Technology and Engineering for Rising Stars), a national middle school program supported by Broadcom Foundation, are eligible to name the top 10 percent of their sixth-grade through eighth-grade participants as Broadcom MASTERS nominees.
