Weekly Schedule

Miss Porter’s School operates on a modular block schedule. Students take two or three classes per 10-week trimester. Classes meet for 90 minutes per day to provide the conditions for the most innovative teaching and learning. Our teachers and students are not limited by the time constraints of short periods or the walls of the classroom.

Benefits of a modular block schedule include:

  • More active and engaging teaching.
  • More focus on fewer things at one time.
  • More impactful and lasting learning.
  • Slower pace of the day, which promotes greater health and wellness.
  • Fewer homework assignments per night, which allows students to engage more deeply with their studies and get to sleep at a reasonable time.

Signature Programs

As our curriculum continues to evolve in response to the changing world and the needs of our students, we are focused on establishing courses and programs that are engaging, relevant, interdisciplinary and experiential in nature. Peruse our Signature Programs Guide to learn more:

Advanced Courses

Our Advanced Interdisciplinary Seminar courses provide rich experiences and cultivate exceptional thinkers. Unlike Advanced Placement (AP) courses that are standardized across the country and designed by individuals who do not know our students, our AIS courses are unique to Porter’s, designed for our students and based on our mission. They combine the intellectual rigor of AP courses with interdisciplinary, experiential and project-based learning. This approach pushes students beyond simply the retention of content for the purpose of passing a test. As a result, our students think more deeply, ask questions, evaluate information and make connections between related topics. Miss Porter’s School is the only place where you can experience these seminars.

Assessment & Feedback

At Porter’s, we practice mastery-based learning, which shifts student focus from grades to growth. We give standards-based feedback in all of our courses. Instead of exam periods, we have Demonstrations of Learning in which students share their learning with the community through projects, presentations, performances and more.

Value of Our Approach to Assessment

Greater transparency and more specific, useful information about student progress.

Development of intrinsic motivation and a growth mindset.

Enhanced consistency, fairness and equity.

Standards-based Grading

The chart below outlines how proficiency ratings generally translate to traditional letter grades.


Letter-grade equivalent:
Student evidence demonstrates consistent mastery of all priority standards and learning objectives. Students in this category may be proficient in some specific skills, but are mostly in the mastery level.


Letter-grade equivalent:
Student evidence demonstrates that the skills required to meet the priority standards and learning objectives for the course are developing and emerging. Students in this category may have achieved proficiency or mastery in some specific skills, but are mostly in the developing level.


Letter-grade equivalent:
Student evidence demonstrates consistent proficiency on all priority standards and learning objectives. Students in this category may have achieved mastery in some specific skills, but are mostly in the proficient level.

No evidence

Letter-grade equivalent:
Students in this category have not yet demonstrated proficiency or growth toward proficiency on the learning objectives for the course.
Mastery Transcript Consortium™

Since 2017, we have been part of the Mastery Transcript Consortium (MTC), a movement of schools aimed at enhancing the student experience and changing the way success is viewed in our society. For most students, success in school has been defined by final grades, averages and test scores.

At MPS, we support a mastery approach to learning, utilizing a system of standards-based ratings and feedback to support students in their learning and growth. Students in the class of 2027 and beyond will have access to the Mastery Transcript™ which will give them the ability to document their passions, achievements and growth over the course of their high school career. While Porter’s will retain the ability to produce traditional transcripts for a student as needed, the engaging and interactive format of the Mastery Transcript™ is designed to capture the interests, abilities and authentic strengths of each learner. It will allow our students to distinguish themselves more fully in the college process in ways that a list of courses and grades cannot.


Benefits of Mastery Transcript

Learning for Today's World

Enables mastery learning and values the higher-order skills necessary for college and career success.

A New Method of Crediting

Mastery credits replace traditional grades and grade point averages (GPAs) and focus on knowledge and skill development.

Meaningful Communication

Students share evidence of their interests, strengths, and skills with colleges and, ultimately, potential employers.
