LBSS Grading Policy and Guidelines *Revised 8-2-2022 FCPS grading and reporting guidelines handbook Grading Philosophy We are professional educators who strive to use assessment and grading to communicate what our students have learned and their level of understanding. The Lake Braddock grading policy will be consistent, fair, and rational and will be communicated appropriately within our school community. 2022-2023 Grading Policy


  • Grades are based on student achievement, knowledge, and skill proficiency demonstrated on course standards. ● The grading policy for each subject will be clearly communicated with parents and students. ● The assessments and assignments that make up a student’s grade will be clearly communicated in the SIS electronic grade book. ● Assignments will be graded and grades will be posted within 7 school days after the due date with the understanding that major projects/papers may require additional time to ensure quality feedback (per FCPS policy). ● Parents and students are encouraged to access the SIS grade book on a regular basis. ● Student progress will be communicated regularly through electronic progress reports. ● All grades entered into the gradebook will relate directly to the standards listed in the Program of Studies or other designated curriculum and should reflect a student’s mastery of content or skills. ● Student’s attendance, effort, attitude or other behaviors will be communicated to parents through report comments or other means that do not include grades. ● Students will not be given extra credit or grades for activities such as bringing in classroom materials, providing parent/guardian signatures, participating in fundraising/charitable events, or participating in non-curricular activities.

Weighted Grades

  • Teachers and collaborative teams will use a weighted grading system that will be reflected in the SIS grading program.
  • Lake Braddock collaborative teams will specify the percentage weight of grades in their syllabi in compliance with the FCPS Grading policy.
  • Collaborative teams will set grading design so that no one assignment/assessment counts more than 20% of the quarter grade.*
  • Collaborative teams will have their own consistency in regards to weighting.
  • In accordance with FCPS policy, homework for practice or preparation for instruction will not count for more than 10% of the grade.
  • Class participation may be included in a student’s grade if it is based on the quality of a student response and not the quantity of responses. If a team will include class participation in a student’s grade, guidelines for assessing must be included in the course syllabus.
  • The number of categories and weighting of grades will be consistent across collaborative teams.
  • Collaborative Teams will organize their grade book using three or four basic categories: Mastery, Skill Demonstration, Knowledge, and Practice. (Teams may combine Skill Demonstration and Knowledge categories.) 
  • All teachers will use a rolling gradebook (RG).

Sample Weighted Categories


  • Comprehensive application of knowledge and skills.


  • Awareness and/or understanding of a subject/standard (facts, information, or skills).

Skill Demonstration

  • The ability to perform a task and apply knowledge related to a standard or concept.


  • Repeated performance or preparation (i.e. homework) in order to acquire proficiency.

Second Chance Assessments

  • For major assessments as defined in the course syllabus, at least one new opportunity to demonstrate proficiency shall be provided multiple times throughout a two week period to any student who completes the initial assessment. In this case, the highest grade that can be earned on the retake is 100%.
  • Second chance assessments must be completed within a timely manner as defined by the Collaborative Team.
  • Second chance assessments may be in an alternate format.
  • Students will need to demonstrate that they have done the necessary preparation to be offered the opportunity on a second chance assessment. Preparation and readiness will be defined by the collaborative team.

Second Chance Assessment Guidelines

Tight (required)

  • All students who completed the initial assessment are eligible for the second chance assessment
  • Second chance assessments required for tests, and other summative assessments (to exclude: Final Exams, PALs exams, music performance assessments, Driver’s Education State Assessment, Concerts/music performances, Science Fair Projects, Project*, Major Writing Assignment with multiple drafts). *Projects with multiple steps/due dates/requirements.
  • Prerequisite to retake assessment includes a targeted learning opportunity for the student. The student needs to demonstrate to the teacher that the student has made sufficient improvement and will perform better on the retake.
  • The assessment grade should reflect and demonstrate the highest level of mastery learning. Highest grade recorded in the grade book is 100%
    • No averaging of assessment grades
    • Highest grade shall be recorded

Loose (CT Discussion)

  • Timeline for second assessment is decided by the Collaborative Team.
  • Format of the assessment: Alternative assessments, formative assessments would be up to the Collaborative Team to decide whether second chances will be given for these opportunities.
  • Format and schedule of intervention and second assessment: requirements, re-teaching/learning opportunity, date for retake, etc. will be decided by the Collaborative Team/teacher.

Grading Assignments and Assessments

  • Students should experience frequent and ongoing assessment and feedback throughout the quarter.
  • Students should receive continual feedback on the quality of work as it relates to the course objectives.
  • Teachers are required to record a minimum of nine and maximum of 18 graded assignments per quarter. Courses that use Standards Based Grading will naturally have numerous grades for each assignment. If teachers use more than 18 graded assignments per quarter, it must be consistent across the teacher team*.
  • The maximum weight of any one assignment and assessment is set at 30%. 
  • Quizzes, tests, examinations, essays, homework, or papers are evaluated and/or graded, returned, and reviewed promptly with the student. Teachers are expected to grade each assignment and post grade to the electronic gradebook within seven school days after the due date with the understanding that major projects/papers may require additional time to ensure quality feedback.
  • 50% is the lowest grade on a 100-point scale that can be entered into SIS. Teachers using a 4 point scale are not impacted by this policy.

Late work

Late work 

  • Major assignments and assessments are to be accepted at a minimum of 2 weeks after the deadline in accordance with county policy. As of the 2022-2023 school year, late work will no longer incur a late penalty. A final due date to submit any late assignment of 1 week before the end of quarter may be made by the Collaborative Team.*


To ensure consistent expectations at Lake Braddock, all courses will use the following Comment Codes to communicate information about assignments:

  • Required Assignment Missing (RAM) - This will be given when a student has not turned in a major assignment that is listed in Mastery Category
  • Retake Required (RR) - If a student scores a failing grade an RR will be listed in SIS to encourage them to attend remediation and retake
  • Minimum Grade Given (MG) - If a student scores below 50% on an assignment an MG will be given to increase their grade to the minimum grade
  • Honor Code Violation Pending (HCP) -  If a student is suspected of violating the LBSS Honor Code an HCP code will be entered into the gradebook while an investigation is conducted.
  • Honor Code Violation (HCV) - If the Honor Council has determined that ya student violated the Lake Braddock Honor Code, then HCV will be entered
