Clayton Valley Charter uses common writing guides and rubrics across English and social science, so students write to the same standards in both. Our tutors are UC Berkeley students who took many of the same courses not long ago, from chemistry to AP Calculus BC.
Tell us about your student, and we’ll match them with a UC Berkeley tutor who fits.
We help Clayton Valley Charter students keep up in their classes, prepare for the SAT and ACT and work on their college essays. Sessions are one-on-one, at your home in Concord, Clayton or Walnut Creek, or online.
Meet our tutors
AP Precalculus to calculus
AP Precalculus at Clayton Valley leads to AP Calculus AB, with a route straight into BC for students who are ready. The idea that carries over is rate of change: how fast a quantity is growing, not just how big it is. A tutor asks your student where a graph is steepest long before any calculus vocabulary appears. Learn more about our math tutoring.
Chemistry in the Earth System
Chemistry sits in the middle of Clayton Valley’s Earth-connected science sequence, between Living Earth and Physics of the Universe. The course asks students to use chemistry to explain things like ocean acidification, which means moving between a molecule and a planet. A tutor asks your student to explain one reaction at the scale of molecules, then at the scale of an ocean. Learn more about our science tutoring.

Fourteen modules in senior ERWC
Senior ERWC works through fourteen reading and writing modules, and each one ends in a written assessment. Because the shared rubric is the same across subjects, it’s worth knowing well. A tutor reads a returned essay with your student against the rubric and picks the one category to raise on the next module. Learn more about our English and writing tutoring.
