Check with your local school district to see if they have a list of available English tutors in your area.
Contact your local library to see if they offer English tutoring to struggling students.
Look for high school students taking advanced placement English who are trying to fulfill volunteer hours. In many districts volunteering in the community is now a graduation requirement.
Get in touch with the English Department at local colleges and universities. Many college students are regularly looking for tutoring jobs to supplement their income.
Check with other parents who have used tutoring services for a recommendation of a good English tutor.
Interview potential candidates and take notice of their use of the language. A person who does not speak well and correctly probably isn't the tutor for you.
Make sure that potential tutors have strengths in both grammar and composition. A tutor who is proficient in both will be able to give better help and instruction.
