RCM

RCM is the most common thing that most piano students use for books and songs. It stands for the Royal Conservatory of Music.

Exams
Students get marked and are approved to go to the next level of piano with exams. There they have to play songs, scales/chords, and other things in front of an examiner. This can be really scary (I've done it myself)! After that, they are marked and usually people get really good results!

Songs/ Technique
Well, everyone knows about songs! But do they know what technique is? Every decent RCM piano player does! They are a set of scales, chords, and arpeggios that exercize someone's fingers. If you haven't heard of them you probably have never taken an exam before.
