delivered the opinion of the Court.
This case concerns the obligation of prisoners who claim denial of their federal rights while incarcerated to exhaust prison grievance procedures before seeking judicial relief. Plaintiff-respondent Ronald Nussle, an inmate in a Connecticut prison, brought directly to court, without filing an inmate grievance, a complaint charging that corrections officers singled him out for a severe beating, in violation of the Eighth Amendment’s ban on “cruel and unusual punishments.” Nussle bypassed the grievance procedure despite a provision of the Prison Litigation Reform Act of 1995 (PLRA), 110 Stat. 1321-73, as amended, 42 U. S. C. § 1997e(a) *520 (1994 ed., Supp. V), that directs: “No action shall be brought with respect to prison conditions under section 1983 of this title, or any other Federal law, by a prisoner confined in any jail, prison, or other correctional facility until such administrative remedies as are available are exhausted.”
The Court of Appeals for the Second Circuit held that §1997e(a) governs only conditions affecting prisoners generally, not single incidents, such as corrections officers’ use of excessive force, actions that immediately affect only particular prisoners. Nussle defends the Second Circuit’s judgment, but urges that the relevant distinction is between excessive force claims, which, he says, need not be pursued administratively, and all other claims, which, he recognizes, must proceed first through the prison grievance process. We reject both readings and hold, in line with the text and purpose of the PLRA, our precedent in point, and the weight of lower court authority, that §1997e(a)’s exhaustion requirement applies to all prisoners seeking redress for prison circumstances or occurrences.
I
Respondent Ronald Nussle is an inmate at the Cheshire Correctional Institution in Connecticut. App. 38. According to his complaint, corrections officers at the prison subjected him to “a prolonged and sustained pattern of harassment and intimidation” from the time of his arrival there in May 1996. Id., at 39. Nussle alleged that he was singled out because he was “perceived” to be a friend of the Governor of Connecticut, with whom corrections officers were feuding over labor issues. Ibid.
Concerning the episode in suit, Nussle asserted that, on or about June 15,1996, several officers, including defendant-petitioner Porter, ordered Nussle to leave his cell, “placed him against a wall and struck him with their hands, kneed him in the back, [and] pulled his hair.” Ibid. Nussle al *521 leged that the attack was unprovoked and unjustified, and that the officers told him they would kill him if he reported the beating. Ibid.
Then, as now, the Connecticut Department of Correction provided a grievance system for prisoners. See id., at 5-18. Under that system, grievances must be filed within 30 days of the “occurrence.” Id., at 11. Rules governing the grievance process include provisions on confidentiality and against reprisals. Id., at 17-18.
Without filing a grievance, on June 10, 1999, Nussle commenced an action in Federal District Court under 42 U. S. C. § 1983; he filed suit days before the three-year statute of limitations ran out on the § 1983 claim. 1 Nussle charged, principally, that the corrections officers’ assault violated his right to be free from cruel and unusual punishment under the Eighth Amendment, as made applicable to the States by the Fourteenth Amendment. App. 38. The District Court, relying on § 1997e(a), dismissed Nussle’s complaint for failure to exhaust administrative remedies. Nussle v. Willette, 3:99CV1091(AHN) (D. Conn., Nov. 22, 1999), App. 43.
Construing § 1997e(a) narrowly because it is an exception “to the general rule of non-exhaustion in § 1983 cases,” the Court of Appeals for the Second Circuit reversed the District Court’s judgment; the appeals court held that “exhaustion of administrative remedies is not required for [prisoner] claims of assault or excessive force brought under § 1983.”
Nussle
v.
Willette,
The Court of Appeals found support for its position in the PLRA’s legislative history. Floor statements, “overwhelmingly suggested]” that Congress sought to curtail suits qualifying as “frivolous” because of their “subject matter,”
e. g.,
suits over “insufficient storage locker space,” “a defective haircut,” or “being served chunky peanut butter instead of the creamy variety.”
In conflict with the Second Circuit, other Federal Courts of Appeals have determined that prisoners alleging assaults by prison guards must meet § 1997e(a)’s exhaustion requirement before commencing a civil rights action. See
Smith
v.
Zachary,
II
Ordinarily, plaintiffs pursuing civil rights claims under 42 U. S. C. § 1983 need not exhaust administrative remedies before filing suit in court. See
Patsy
v.
Board of Regents of Fla.,
In 1980, however, Congress introduced an exhaustion prescription for suits initiated by state prisoners. See Civil Rights of Institutionalized Persons Act, 94 Stat. 352, as amended, 42 U. S. C. § 1997e (1994 ed.). This measure authorized district courts to stay a state prisoner’s §1983 action “for a period of not to exceed 180 days” while the prisoner exhausted available “plain, speedy, and effective administrative remedies.” § 1997e(a)(l). Exhaustion under the 1980 prescription was in large part discretionary; it could be ordered only if the State’s prison grievance system met specified federal standards, and even then, only if, in the particular case, the court believed the requirement “appropriate and in the interests of justice.” §§ 1997e(a) and (b). We de
*524
scribed this provision as a “limited exhaustion requirement” in
McCarthy
v.
Madigan,
In 1996, as part of the PLRA, Congress invigorated the exhaustion prescription. The revised exhaustion provision, titled “Suits by prisoners,” states: “No action shall be brought with respect to prison conditions under section 1983 of this title, or any other Federal law, by a prisoner confined in any jail, prison, or other correctional facility until such administrative remedies as are available are exhausted.” 42 U. S. C. § 1997e(a) (1994 ed., Supp. V).
The current exhaustion provision differs markedly from its predecessor. Onee within the discretion of the district court, exhaustion in cases covered by §1997e(a) is now mandatory. See
Booth
v.
Churner,
Beyond doubt, Congress enacted § 1997e(a) to reduce the quantity and improve the quality of prisoner suits; to this
*525
purpose, Congress afforded corrections officials time and opportunity to address complaints internally before allowing the initiation of a federal case. In some instances, corrective action taken in response to an inmate’s grievance might improve prison administration and satisfy the inmate, thereby obviating the need for litigation.
Booth,
Congress described the cases covered by § 1997e(a)’s exhaustion requirement as “actionfs] . . . brought with respect to prison conditions.” Nussle’s case requires us to determine what the §1997e(a) term “prison conditions” means, given Congress’ failure to define the term in the text of the exhaustion provision. 3 We are guided in this endeavor by the PLRA’s text and context, and by our prior decisions relating to “[s]uits by prisoners,” § 1997e. 4

As to precedent, the pathmarking opinion is
McCarthy
v.
Bronson,
We did not “quarrel with” the prisoner’s assertion in McCarthy that “the most natural reading of the phrase ‘challenging conditions of confinement,’ when viewed in isolation, would not include suits seeking relief from isolated episodes of unconstitutional conduct.” Id., at 139. We nonetheless concluded that the petitioner’s argument failed upon reading the phrase “in its proper context.” Ibid. We found no suggestion in § 636(b)(1)(B) that Congress meant to divide *527 prisoner petitions “into subcategories.” Ibid. “On the contrary,” we observed, “when the relevant section is read in its entirety, it suggests that Congress intended to authorize the nonconsensual reference of all prisoner petitions to a magistrate.” Ibid. The Federal Magistrates Act, we noted, covers actions of two kinds: challenges to “conditions of confinement”; and “applications for habeas corpus relief.” Id., at 140. Congress, we concluded, “intended to include in their entirety th[ose] two primary categories of suits brought by prisoners.” Ibid.
“Just three years before [§ 636(b)(1)(B)] was drafted,” we explained.in

trained solely and precisely on proof requirements: what injury must a plaintiff allege and show; what mental state must a plaintiff plead and prove. Proof requirements once a case is in court, however, do not touch or concern the threshold inquiry before us: whether resort to a prison grievance process must precede resort to a court. We have no reason to believe that Congress meant to release the evidentiary distinctions drawn in

and
Farmer
from their moorings and extend their application to the otherwise invigorated exhaustion requirement of § 1997e(a). Such an extension would be highly anomalous given Congress’ elimination of judicial discretion to dispense with exhaustion and its deletion of the former constraint that administrative remedies must be “plain, speedy, and effective” before exhaustion could be required. See
supra,
at 524;
Booth,
Nussle contends that Congress added the words “prison conditions” to the text of §1997e(a) specifically to exempt excessive force claims from the now mandatory exhaustion requirement; he sees that requirement as applicable mainly to “ ‘prison conditions’ claims that may be frivolous as to subject matter,”
*530
Furthermore, the asserted distinction between excessive force claims that need not be exhausted, on the one hand, and exhaustion-mandatory “frivolous” claims on the other, see
id.,
at 2,26-27, is untenable, for “[e]xcessive force claims can be frivolous,”
Smith,
Other infirmities inhere in the Second Circuit’s disposition. See
McCarthy,
Under Nussle’s view and that of the Second Circuit, moreover, bifurcation would be normal when a prisoner sues both *531 a corrections officer alleged to have used excessive force and the supervisor who allegedly failed adequately to monitor those in his charge. Tr. of Oral Arg. 31. The officer alone could be taken directly to court; the charge against the supervisor would proceed first through the internal grievance process. Similarly split proceedings apparently would be in order, under the Second Circuit’s decision, when the prisoner elects to pursue against the same officers both discrete instance and ongoing conduct charges.
Finally, we emphasize a concern over and above the complexity augured by the Second Circuit’s disposition: Scant sense supports the single occurrence, prevailing circumstance dichotomy. Why should a prisoner have immediate access to court when a guard assaults him on one occasion, but not when beatings are widespread or routine? See
Smith,
*532 * * *
For the reasons stated, we hold that the PLRA’s exhaustion requirement applies to all inmate suits about prison life, whether they involve general circumstances or particular episodes, and whether they allege excessive force or some other wrong. Cf.
Wilson,
It is so ordered.
Notes
The Second Circuit has held that §1988 actions in Connecticut are governed by that State’s three-year statute of limitations for tort actions.
Williams
v.
Walsh,
Another provision of the PLRA, 18 U. S. C. § 3626(g)(2) (1994 ed., Supp. V), the court observed, does define “prison conditions.”
Nussle
v.
Willette,
The parties dispute the meaning of a simultaneously enacted provision, § 3626(g)(2), which concerns prospective relief, and for that purpose, defines the expression “civil action with respect to prison conditions.” See supra, at 522, n. 2 (noting, inter alia, divergent constructions of Second and Third Circuits). We rest our decision on the meaning of “prison conditions” in the context of § 1997e, and express no definitive opinion on the proper reading of § 3626(g)(2).
In reaching its decision, the Second Circuit referred to its “obligation to construe statutory exceptions narrowly, in order to give full effect to the general rule of non-exhaustion in §1983.”
Title 28 U. S. C. § 636(b)(1)(B) provides in relevant part:
“(b)(1) Notwithstanding any provision of law to the contrary—
“a judge may . . . designate a magistrate to conduct hearings, including evidentiary hearings, and to submit to a judge of the court proposed findings of fact and recommendations for the disposition, by a judge of the court,... of applications for posttrial relief made by individuals convicted of criminal offenses and of prisoner petitions challenging conditions of confinement.”
Other provisions of § 1997e that refer to “prison conditions” would have less scope under the Second Circuit’s construction of the term. Section 1997e(c)(l) provides for dismissal on the court’s own initiative of “any action brought with respect to prison conditions” that is “frivolous [or] malicious.” No specific incident complaint would be subject to that prescription under the view that such suits do not implicate “prison conditions.” Further, § 1997e(f)(l) provides that pretrial proceedings in “any action brought with respect to prison conditions” may be held at the prison via telephone, video conference, or other telecommunications technology so that the prisoner need not be physically transferred to participate. Surely such arrangements would be appropriate in Nussle’s case and *532 others of its genre. But on what authority would these practical procedures rest if cases like Nussle’s do not qualify as actions regarding “prison conditions”?
