		| Abstract: | 
		We describe some of the strategies and procedures that we have developed for the confirmation of transiting-planet candidates identified by widefield photometric surveys. We report the relative frequency of several types of astrophysical false positives found among 456 candidates from the Vulcan, TrES, and HAT surveys. |
