The NGTM Colloquia are no longer held. North Dakota 2011 was the last such gathering. The 2014 National Great Leaders Summit was held in North Carolina while the 2016 International Great Teachers Leadership Summit (IGTLS) was held in Bryce Canyon, UT.
In 2017, the IGTLS was held at Lake Geneva, WI with the first NGTM Tribal Gathering held in Hendersonville, NC in March 2018. These events are designed to provide informative, reflective, and innovative opportunities for Great Seminar leadership world-wide.
