MEMORANDUM **

Karen Krushwitz, a former graduate student and teaching assistant, appeals from the district court’s grant of summary judgment in favor of her former university, U.C. Berkeley. Krushwitz alleges that U.C. Berkeley discriminated against her and failed to accommodate her disability, and brings claims under Title VII, Titles I & II of the Americans with Disabilities Act (“ADA”), and Section 504 of the Rehabilitation Act. 1 We affirm.

*715 First, Krushwitz’s contention that the grant of summary judgment must be reversed because the district court procedurally erred is not persuasive. It is true that “[a] moving party without the ultimate burden of persuasion at trial ... has both the initial burden of production and the ultimate burden of persuasion on a motion for summary judgment.” Nissan Fire & Marine Ins. Co. v. Fritz Cos., 210 F.3d 1099, 1102 (9th Cir. 2000). A district court, however, has authority to request supplemental briefing under Rule 56, and determining the relevant dates did not require the district court to weigh evidence or assess credibility. Krushwitz, moreover, did not object to providing additional information to the court.

Krushwitz’s employment discrimination claims are brought under Title VII and Title I of the ADA. She did not file a timely discrimination charge with the EEOC, required as a precondition for filing suit under these provisions. 42 U.S.C. § 12117(a); 42 U.S.C. § 2000e-6(e)(l). Nor was there a triable issue of fact as to whether Krushwitz’s disability equitably tolled the limitations periods. This is not one of those “exceptional circumstances, such as institutionalization or adjudged mental incompetence of the litigant,” under which equitable tolling is appropriate. Grant v. McDonnell Douglas Corp., 163 F.3d 1136, 1138 (9th Cir. 1998); see also Johnson v. Lucent Techs. Inc., 653 F.3d 1000, 1010 (9th Cir. 2011).

We turn next to the student discrimination claims, brought under Title II of the ADA and Section 504 of the Rehabilitation Act. The district court correctly determined and applied the relevant limitations period for the Title II claim. See Sharkey v. O’Neal, 778 F.3d 767 (9th Cir. 2015) (holding that a three year limitations period applies). Even if we assume that a three year limitations period applies to the Section 504 claim, Krushwitz’s claims are still time-barred. We are not persuaded that the untimely EEOC filing tolled the statute of limitations ■ for the student claims. See Johnson v. Railway Express Agency, Inc., 421 U.S. 454, 466, 95 S.Ct. 1716, 44 L.Ed.2d 295 (1975).

AFFIRMED.
