International Physics & Astronomy Educator Program

Applications for the 2024 LIGO International Physics and Astronomy (IPA) program are now closed. Applications for the 2025 program will open November 2024. Full details about the program and the application form are found below.

2019 IPA Cohort

LIGO's International Physics and Astronomy (IPA) program for educators is an exciting one-week intensive program geared towards high school educators from around the world. Based at the LIGO Hanford Observatory, the IPA program offers participants opportunities to discuss with and hear from experts in modern physics and astronomy, tour sites of historic and scientific interest, and test out classroom activities that they can use in their home institutions. Topics of discussion range from nuclear physics to the emerging fields of gravitational wave and multi-messenger astronomy. The intent of the IPA program is to promote the teaching of modern physics in high schools by providing teachers with the opportunity to deepen their physics knowledge and fuel their passion for physics in an environment where teachers from around the world can exchange knowledge and experience.

2019 IPA OSB Activities

Teachers work in teams playing the role of student while learning new hands-on activities to be applied in their classrooms around the world.

The 2024 IPA program will be held at the LIGO Hanford Observatory in eastern Washington State, Sunday, July 14 to Saturday, July 20, 2024. Participants must be able to attend the entire program.

Since the IPA program is offered in English, applicants should be fluent in speaking and writing the English language.

If you have any questions please reach out to outreach@ligo-WA.caltech.edu.


Program Cost

The fee for the program is $300, which is a small fraction of the full program cost. The fee helps cover participant accommodations, meals, and transportation to and from LIGO. Remaining costs are covered by LIGO and other supporters.


Travel Cost

Participants are responsible for arranging and paying for their travel to and from the Tri-Cities, WA, including visas if necessary. Please be mindful of your local travel restrictions and requirements. For those flying in for the program, ground transportation to and from the Tri-Cities Airport in Pasco, WA will be provided by LIGO.

2019 IPA Social Time

Group dinners with LIGO staff provide opportunities for participants to get to know each other better, and to process and discuss the learning taking place each day. Here, LIGO staff scientist, Greg Mendell (left foreground), talks physics with teachers over a relaxed meal. LIGO Associate Director for Operations, Fred Raab (4th 'head' from the front right) is also always eager to meet with educators and answer questions.

2019 IPA LVEA tour prep

2019 IPA attendees prepare to get a behind-the-scenes tour of LIGO Hanford Observatory. Hair nets and booties keep excessive dust and dirt out of the area being toured, while the goggles protect eyes from possible stray near-infrared laser light. LIGO staff scientist, Jenne Driggers (black tee-shirt) joins them for the tour.




When filling out the IPA Program application you will be asked to provide:

  • Basic information about you and your school, such as name and contact information.
  • Basic information about your teaching experience, such as how many years you have been teaching and subjects you teach.
  • Answer the following questions:
    • What does inquiry based learning mean to you?
    • Describe one of your favorite lessons/activities/labs that you do in your class?
    • What do you hope to gain from participating in the IPA Program?
    • How do you plan to share what you learn during the IPA Program?
    • In a short 1-2 minute video explain what interests you about modern physics. You will have the opportunity to paste the link to your video in the answer window or indicate you will email the video to our outreach coordinator at a later time. All videos must be received by January 31, 2024.
