1.  Provide a quiet, distraction free practice setting (no TV, other children, etc) with adequate lighting, piano bench, and an adjustable foot support for younger students.  

2.  Help your piano student learn to manage time for practice.  Discuss the daily activity schedule with your child.  Agree on a set time to practice every day and insist it be respected by everyone in the family.

3.  Daily practice sessions of 10-30 minutes for an elementary student, 30-45 minutes for middle school age students, and 45-60 minutes for a high school student should bring them to the next piano lesson well prepared if the
home practice time is used wisely.  

4.  The quality and frequency of piano practice sessions are as important as the length.  More effective practice results are often achieved with shorter practice sessions several times per day, especially with younger piano students.

5.  No child, especially a beginning piano student, should be expected to do all of their practicing alone.  Help them read and follow practicing directions.  Perhaps even play the pieces with them and sing along.  You will soon appreciate the effort required by the student.  And children always enjoy teaching an adult something new.  

6.  Make your child's music a part of your daily adult activities at home.  Often the best time for effective piano practice is while the adult is preparing for family mealtime.  This provides the student with the nearby supervision of an interested adult, the parent with enjoyable background music while working, an eager performer for an appreciative audience, a positive musical experience and fun for all.

Expect ups and downs in interest level and progress. Give positive, gentle encouragement and honest praise.  A reward system can be helpful at times, even if only a sparkly sticker because the piano student remembered to practice without being reminded.
