Teacher certification is important - to you! Certification says the teacher cares enough about their students to put in the extra effort necessary to earn it. That's why all the best teachers have earned their certification.
ACM Certification is especially challenging, as it is "proof of the pudding." It's earned by student performance and achievement, not just teacher book learning, and it must be renewed annually! National, about 225 teachers "make the grade" each year.
Although I am truly privileged and honored to be a member of this select group of teachers, it is your student who is the ultimate beneficiary.
