AMGA Single Pitch Instructor Certification



The internationally recognized Single Pitch Instructor (SPI) Program teaches climbing instructors to proficiently facilitate and instruct the sport of rock climbing in a single pitch setting. This November, CMRCA will host an SPI Course and Assessment facilitated by AMGA Guide Rainbow Weinstock.

Benefits of Certification

  • It significantly improves the instructor’s skill sets and integrates into the next level of training, the AMGA Rock Instructor Course.
  • The program is for current, active rock climbers who have a real desire to teach rock climbing to novices in a single pitch setting.
  • The SPI Course is a 27-hour training course that normally runs as three consecutive nine-hour days or day classes with evening sessions.
  • The SPI Assessment is a minimum of 16 hours run over a two-day period.
  • Certification lasts for three years as long as the candidate keeps current AMGA Membership and First Aid Certification.
  • After three years current SPI’s can re-take the SPI Assessment to regain the SPI certification.
  • Taking any higher level AMGA Course also re-certifies the SPI certification for another three years.

Step 4: Prepare for the SPI Assessment

The pre-requisites for the SPI Assessment are not the same as the course. Please note that taking the course does not mean you will be ready to take the assessment. At the end of the course, your instructor will decide whether or not you are ready for the assessment.  Candidates must provide all of their own equipment for the assessment.  SPI Equipment List

Pre-Requisites for the Assessment
  • You are a current member of the AMGA.
  • You have successfully completed an AMGA Single Pitch Instructor Course.
  • You have led a minimum of 40 traditional routes, most of which should be 5.6 and on a variety of rock types.
  • You are able to comfortably lead 5.6 traditional routes, which means you place protection.
  • You are able to comfortably climb 5.8 on top rope.
  • The SPI Assessment can be taken directly following the SPI Course if the candidate successfully completed the course and meets the assessment prerequisites. However, it is highly recommended that the SPI Course candidate take time practicing and consolidating the skills learned on the course before assessment (6-12 months).
  • You do not need First Aid training to take the course or assessment. However, it is your responsibility to hold appropriate medical certification for the location that you are working in.

About the Instructor


Rainbow has been fortunate enough to climb, work and adventure throughout the U.S. and abroad, including alpine Patagonia, the Dolomite spires of Italy, jungles of Venezuela, walls of Mexico and the absurdly good Canadian granite.  The tremendous diversity and access of adventure and rock to be found around Boulder is what continues to excite him for the climbing and guiding opportunities nearby. Whether high on the Diamond on Long’s Peak or cragging in Eldorado Canyon, Rainbow continues to note that it is just as important who you are climbing with as it is what you are climbing on.
