A future investment.

Our Pricing

Principia offers 1:1 tutoring, test prep, and college consulting services on an hourly basis, remotely across the country and in-person at our McLean office. We believe 1:1 sessions are the most effective, efficient, and flexible way to learn and build a mentoring relationship.

Our Process

The first step for new families is to set up a complimentary 20-minute consultation with our coordinators so we can learn more about your student’s areas for improvement and learning style to make the appropriate teacher recommendation.

After you’ve let us know you’d like to move forward, our office will be in touch to send over our parent agreement and instructions on how to complete your account setup — we use the Teachworks platform to share instructor feedback after every session as well as for billing and tracking purposes.

 FAQs

  • We bill at the end of the month for that month's sessions using Stripe, a securely encrypted, PCI-compliant card processing system. If you'd prefer to preload your account via check, please contact info@principiatutors.com to make arrangements.

  • For parent-teacher consultations, we recommend utilizing the first or last 15 minutes of the session. Please reach out 48-hours in advance so your instructor can plan their session accordingly. For extended consultations, please reach out via email to schedule—these meetings will be billed in 15-minute increments at the instructor's current hourly rate.

  • We believe that students learn best when they build a strong mentoring relationship with their instructors. To create that space, all private tutoring sessions are 1:1 except in rare cases where the instructor has requested the parent to join for a specific reason.

  • Principia understands that our clients have busy schedules. To that end, we're happy to cancel or reschedule sessions and appointments with at least 48-hour notice. The best way to reach out is via email — please contact your instructor and cc info@principiatutors.com so we can adjust schedules and calendars accordingly.

    In cases of inclement weather and emergencies, we may waive this policy. Principia's client coordinators will make a determination on fee waivers for late cancellations due to emergencies. Please note that all no-shows and cancellations made on short notice will be charged the full amount of the scheduled time billed at the instructor's hourly rate.

  • Our instructors spend significant time throughout the week prepping for their sessions, often far in advance of our 48-hour cancellation policy. Uncompensated last-minute cancellations are one of the top reasons for instructor turnaround; our policy is designed to retain the best instructors over the long-term to provide a consistent learning experience for our students, often over many years.
