Plymouth-Canton middle schools switch to 5‑point grading scale; district says gaps are closing

Plymouth‑Canton Community Schools officials presented data to the Board of Education showing the district’s new Middle School Common Grading Framework produced fewer failing semester grades and narrowed demographic performance gaps.

The framework replaces the traditional 100‑point averaging system with an equal‑interval five‑point scale and sets common categories and weightings: summative assessments (60%), learning checkpoints (35%) and practice (5%). Anthony Reller, introduced as executive director of bridal school education, told the board the 5‑point scale corrects what the district called a mathematical inaccuracy in the previous averaging method, where very low scores disproportionately pulled down averages.

The district reported semester‑one passing rates (A–D) increased across English language arts, mathematics, science and social studies when compared with a four‑year baseline. Reller said the percentage of E grades fell from 5.5% in 2021–22 to 1.2% in 2024–25 while A‑rates modestly declined, a pattern district leaders said argues against grade inflation and instead reflects more accurate representation of mastery.

Reller and district staff outlined practices that accompany the scale: common task categories, agreed grading language for adults and students, and expectations for multiple opportunities to demonstrate learning. He said teachers may accept late practice work up to unit assessment deadlines and that teachers will provide feedback on practice without necessarily assigning it heavy grade weight.

Student co‑chair Josh Patterson asked whether students would routinely be granted retake opportunities; Reller said departments set common practices and that multiple attempts are expected for many assessment types. Board members asked about family response. Administrators said they had received a handful of inquiries last year during soft rollout and few parent complaints in the first mandatory implementation year; one counselor forwarded a student‑reported improvement story.

District staff said the change is intended to make grades a more valid communication about student mastery, and to reduce the weight of compliance tasks (for example, credit for completing homework) on final grades. Reller said middle‑level and high‑school teams have coordinated work so the high school will have clearer transmission of what middle school grades mean for incoming students.

Board members asked about transfer students from other districts; Reller said other districts use a range of approaches but none he knew matched PCCS’s exact technical implementation.

The presentation included appendices with documentation and a parent‑facing video the district provided earlier in the school year. District leaders said they will continue to collect semester‑two outcomes and teacher feedback, and they plan additional professional development to support teachers using the framework.

The board did not take a formal vote on the presentation; the district framed the item as an informational, implementation update.
