I’m using this goal described here

1. Expect a high level of achievement with each piece. Near enough is good enough, but near enough means at tempo and with flow and with communicative intent, not a bald reading-through without any sense of what the music means. So performances need dynamics, articulation, voicing and balance, used of pedal and so forth! If this seems too big an ask you need to be looking at easier material, not at lowering your standards.

2. Start with a slew of material. Let’s stick with our hypothetical Grade 5 student. Week One of 2013, assign two Grade 5 standard pieces (meeting your student’s expectations) but also give a couple of pieces from Grade 1 or Preliminary or even P Plate Piano 3 standard, along with another at Grade 2 or 3 standard. You’ll be assigning another two pieces the next week (probably both at the Grade 1 end of the spectrum), and you need things to be moving right from the start.

3. Explain directly and clearly what your expectations are regarding each piece, particularly in regard to time frames. For a piece of music 4 or more grades below their current exam-standard, tell students they have one week to learn the piece, two weeks if there’s some catastrophe like a house fire. Make it understood that these pieces are not supposed to take a whole term to master, that the whole point is learn these easier pieces as quickly as possible and move on.
