Grading Philosophy

At Tremper we use a 90/10 grading system.  

  • 90% of students’ grades are based on summative assessments that may include performance projects, essays, tests, etc. which show each student’s mastery of curriculum.  
  • 10% of students’ grades are based on formative (practice) work and assessments that provide students with opportunities to gain the acquired skills and gauge their mastery of curriculum prior to a summative assessment. 


Current research into best practices indicates that formative assignments and assessments should be “low stakes.” This means we don’t “punish” kids for academic practice. This process helps students to know where they are in their learning going into a summative assessment.  It makes their demonstration of mastery the bulk of the grade.  

  • A 90/10 Grading system allows students to make mistakes as part of the learning process and builds students’ skills, persistence, and resilience.
  • A consistent structure and application in grading is equitable. 
  • It provides equal opportunities for success.
  • It clearly and equitably communicates evidence of learning.
  • Having consistent grading practices provides clarity for parents and students about how they will be graded at Tremper.
