I was a regular in classrooms and programmed teaching until the last three years of my principalship years. It then became more incidental but was maintained. Principals need to know their students and the best way to achieve that is by teaching them. I most certainly read all reports to parents written by teachers and wrote my own comments to the child on each report. As a principal I found children valued knowing I valued them. Part of this was possible because I engaged my leadership group fulsomely in the business of school operations. Sharing in this way enabled me to share time with children.
Things CAN become busy from an adminstrative viewpoint but we neglect establishing and maintaining meaningful connnections with students at our peril.

ALWAYS REMEMBER THE PRIME FOCUS OF YOUR ROLE
