Russell Bishop's 'Leading to the North East' identifies a quadrant where students have a 1 in 4 chance of achieving to their full potential.
This top right hand quadrant is where teachers have strong relationships with their students along with strong explicit teaching skills.
Therefore students have a 3 in 4 chance of not achieving to their full potential if they are being taught by teachers in the 3 other quadrants.
All parts of the above are paramount to be working in the far right quadrant.
Part 3 is the bit where when teachers monitor students' progress and the impact of the processes of learning and modify practices accordingly this is when leading in the north west can be sustained.
