The actual techniques used in the school have been classified by the US government, but several official sites exist to give a general overview of the curricula.

extreme temperatures
waterboarding - being tied to a board with the feet higher than the head and having water poured into the nose
noise stress - playing very loud and dissonant music and sound effects. Recordings have been reported to include babies wailing inconsolably, cats meowing, and irritating music (including a record by Yoko Ono)<1>
sexual embarrassment
religious dilemma - being given the choice of seeing a religious book desecrated or revealing secrets to interrogators.
flag desecration
prolonged cramped or restrictive confinement
sleep deprivation/starvation
excrement familiarization/humiliation
mock execution
overcoming food aversion (eating bugs, roadkill, dumpster diving, urine drinking)
