  • Outstanding Interpersonal and Motivational Skills

QUALIFICATIONS: All Cornerstone tutors have Master's degrees or PhD's and extensive teaching experience. Cornerstone also looks for individuals who have outstanding interpersonal and communication skills. Once a potential tutor meets these qualifications, Cornerstone has the candidate tutors take several evaluation tests to ensure mastery level understanding of the relevant subject area.    An exhaustive background check is conducted as well.  Cornerstone selects only those tutors who measure up to our rigorous standard of excellence.

TRAINING: Tutor training at Cornerstone is extensive. After meeting initial requirements, our tutors must train for between 30 and 100 hours for each test they will teach. During this time, our tutors are taught proprietary teaching methods and strategies, observe tutoring sessions, and analyze and annotate all curricular materials.  As a result, our tutors are quite simply the best in the industry.  

All of Cornerstone's tutors possess a minimum of a Master's Degree along with teaching experience, and are experts in their subject areas. Call us today for a free academic consultation!


The director and owner of Cornerstone, Art is a test prep expert with over twenty years experience tutoring hundreds of students in the Boston area.  Students continue to work with Art to get top scores on their SATs, ACTs, SSATs, and other standardized tests.  Many students say that after their first lesson, they learned more SAT strategies than they did during an entire course before working with him.  Students also love the instant connection with Art - the immediate understanding that he knows what to teach them and in a way that makes perfect sense.  Art is a graduate of Bucknell University where he earned his Bachelor's in Civil Engineering.  He then graduated from MIT where he earned his Master's, also in Civil Engineering.  In his free time, Art enjoys running (he ran his first Boston Marathon in 2014), cycling, and reading.
