Sierra College holds formal commencement ceremonies at its Rocklin, Nevada County, and Tahoe‑Truckee campuses, where graduates participate in a full commencement experience including cap, gown and tassel ordering, guest arrangements, and official diploma conferral.

For the ceremony, Sierra College confirms that traditional academic regalia (graduation cap and graduation gown) is required. Alongside the standard cap, gown and tassels set, the College specifically provides and encourages use of additional regalia — honor cords, stoles, and honor tassels — to recognize academic achievement, honor‑society membership, or participation in student support programs or cultural identity initiatives.

Students who complete the College’s Honors Program (15 units of honors coursework plus a minimum GPA) are awarded a special gold honor stole to wear with their graduation gown. If a student completes the honors coursework but does not meet the GPA threshold, they receive instead a maroon‑and‑white double honor cord. Additionally, members of the honor‑society Phi Theta Kappa (PTK) are eligible for an official blue‑and‑gold double honor cord for commencement.

The commencement‑program documentation emphasises that Sierra College “celebrates the academic achievements of its graduates through the awarding of honor tassels, cords and the Phi Theta Kappa stole,” and explicitly “welcomes the wearing of stoles, cords and other adornments that reflect a graduate’s participation in programs that foster student success, cultural identity and academic excellence.”

What remains unspecified publicly: there is no published comprehensive “academic‑regalia chart” specifying universal gown colour (e.g., black vs school colours), tassel colour by degree or major, or faculty regalia standards (hoods, gown trim, doctoral robes). The publicly available documents do not define a mandatory colour‑code for base gowns or tassels. Instead, the focus is on additional adornments (stoles/cords) for honours or program‑based recognition.

In practice, Sierra College’s commencement ceremonies appear to rely on a standard cap, gown and tassel set, augmented by honour cords or stoles to mark achievement or affiliation — allowing personalization and recognition while maintaining a coherent academic‑regalia framework.
