OPINION
FABE, Chief Justice.

I. INTRODUCTION

In June 1996 the Miller's Reach Fire burned over 37,000 acres in the Matanuska/Susitna *101 Valley. The State, Department of Natural Resources, Division of Forestry responded to the initial fire and took control of firefighting operations from the local fire departments on the scene. A group of landowners who suffered damage to their homes and property brought suit, claiming that the State's firefighting activities were negligently conducted. The superior court certified a plaintiff class. Two motions to dismiss were filedone based on an alleged lack of a duty of care, the other based on discretionary function immunity under AS 09.50.250. The superior court denied the first motion and granted the second. The plaintiffs appeal these decisions. The State cross-appeals on both its first motion to dismiss and the certification of the class.

II. FACTS AND PROCEEDINGS

This appeal is closely related to the proceedings in Angnabooguk v. State, Department of Natural Resources, Division of Forestry, and our opinion in Angnabooguk resolves most of the issues in this appeal.[1]
The relevant facts are identical to those that were considered in Angnabooguk.[2] Both appeals concern the Miller's Reach Fire that burned from June 2 through June 15, 1996 in the Matanuska/Susitna Valley.
Two suits were brought in superior court by different groups of landowner plaintiffs, alleging negligence on the part of the State, Department of Natural Resources, Division of Forestry (Forestry): the case at bar, Bartek, before Superior Court Judge Beverly W. Cutler, and Angnabooguk, before Superior Court Judge John Reese. Plaintiffs filed this action on March 24, 1998. On November 5, 1998, the action was converted into a class action when Judge Cutler certified a plaintiff class. The certified class is apparently large enough to contain all of the plaintiffs in Angnabooguk. The class was defined as:
All owners of real and/or personal property who have suffered tangible property damage and other legally compensable losses as a result of the Miller's Reach fire.
Two motions to dismiss were filed by Forestrythe first on the basis of an alleged lack of a duty of care, the second on the basis that discretionary function immunity under AS 09.50.250 barred the suit. The superior court denied the first motion, but granted the second. Judge Cutler issued an oral ruling explaining her decision on February 9, 1999.
A few months later, in the parallel Angnabooguk action, Forestry moved to dismiss in that action under three different theories the applicable statute of limitations, lack of a duty of care, and immunity under the Alaska Tort Claims Act, AS 09.50.250. Judge Reese dismissed the case under the immunity theory; the order of dismissal did not mention the other two theories. In doing so, Judge Reese adopted Judge Cutler's February 9, 1999 oral ruling.[3]

III. STANDARD OF REVIEW

This appeal requires this court to review the superior court's grant of class certification, which is reviewed for abuse of discretion.[4]

IV. DISCUSSION

There are three issues in this appeal and cross-appeal: (a) whether Forestry owed a duty of care to the plaintiff class; (b) whether Forestry is immune from the plaintiffs' claims under AS 09.50.250; and (c) whether the superior court abused its discretion by certifying the plaintiff class. The first two questions have already been resolved by our opinion in Angnabooguk,[5] and we will not revisit these issues here. In Angnabooguk, we held that Forestry owed the plaintiffs a duty of care,[6] and we reversed the dismissal of the plaintiffs' claims, because AS 09.50.250 does not immunize all claims of negligent firefighting alleged by the plaintiffs.[7] Therefore, *102 in this appeal we need only address the issue of whether the Bartek class was properly certified.
Class certification is governed by Alaska Civil Rule 23, which is patterned after Federal Rule of Civil Procedure 23.[8] For this reason, we have noted that federal decisions will be "especially persuasive" in interpreting Alaska Civil Rule 23.[9]
Forestry makes two general claims to support its argument that the superior court abused its discretion by certifying the plaintiff class: (1) the court should have held an evidentiary hearing and allowed discovery before granting certification; and (2) the requirements of Civil Rule 23 were not satisfied. These will be considered in turn.

A. It Was Within the Superior Court's Discretion to Determine that No Evidentiary Hearing or Discovery Was Required Prior to Class Certification.

Forestry claims that an evidentiary hearing, or an opportunity for discovery, should have been required before the superior court certified the class. Forestry made these claims below as well, but the superior court granted class certification without an evidentiary hearing or discovery on the class certification issue.
Forestry argues that because the superior court certified the class without permitting discovery or holding an evidentiary hearing, it failed to perform "the rigorous analysis the United States Supreme Court had in mind." However, no authority supports the proposition that discovery or an evidentiary hearing is always required. Some authorities stand for the proposition that discovery will sometimes be required, but only in particular circumstances where a "fuller development" of the record is needed or there is an insufficient basis for certification in the pleadings; however, those courts do not hold that discovery or an evidentiary hearing is required in every case.[10]
Similarly, the Eleventh Circuit requires an evidentiary hearing if there is any "doubt" about certification issues; however, this rule appears to have been applied only to benefit plaintiffs whose request for certification had *103 been denied without a hearing.[11]
And other jurisdictions have explicitly disavowed the evidentiary hearing requirement before class certification. As the Massachusetts Supreme Judicial Court noted:
The defendants suggest that the judge abused his discretion because he certified the class without holding an evidentiary hearing. Although it is within a judge's discretion to hold an evidentiary hearing, there is no such requirement. Here, the motion judge reviewed the pleadings, affidavits, briefs, and the earlier memorandum on summary judgment in light of the requirements of [R]ule 23. There is no indication that a reasoned decision on the motion for class certification required anything more.[12]
Other courts have similarly noted that a court may hold an evidentiary hearing if it concludes that one is needed, but that the matter is within the court's discretion.[13] An evidentiary hearing or discovery may not be needed because the plaintiffs may establish compliance with Rule 23 through the pleadings alone; however, the plaintiffs who choose this approach must establish a factual basis that satisfies all the requirements of Rule 23.[14]
Therefore, an evidentiary hearing or discovery is not always required before class certification; it is up to the trial court to determine whether there are factual disputes which should be resolved at an evidentiary hearing after discovery. It is within the discretion of the superior court to decide whether to hold an evidentiary hearing or permit discovery before granting class certification.

B. The Superior Court May Wish to Reconsider Whether the Requirements of Rule 23 Are Met on Remand.

Alaska Civil Rule 23 contains two sets of requirements for certification, in sections (a) and (b) of that rule. Rule 23(a) contains *104 four separate threshold requirements ("prerequisites"), all of which must be met:
(a) Prerequisites to a Class Action. One or more members of a class may sue or be sued as representative parties on behalf of all only if (1) the class is so numerous that joinder of all members is impracticable, (2) there are questions of law or fact common to the class, (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class, and (4) the representative parties will fairly and adequately protect the interests of the class.
Rule 23(b) imposes additional requirements, which can be satisfied in any one of three ways under Rule 23(b)(1), (2), or (3). Under Rule 23(b)(3), considered by the superior court, the court must find that "the questions of law or fact common to the members of the class predominate over any questions affecting only individual members, and that a class action is superior to other available methods for the fair and efficient adjudication of the controversy."[15]
The superior court found that the Bartek class satisfied the requirements of Rule 23(a) and 23(b)(3). We need not review this ruling at this time, because at the time she granted the motion to dismiss, Judge Cutler indicated that she might be inclined to reconsider the issue of class certification:
[I]f the court were not taking this action with the complaint right now, ... the court [would] probably sua sponte revisit the issue of class certification.... [M]aybe this case should be like one of those cases where ... 100 or 200 people around the state all join in challenging the new breath test for DWI or something. Maybe we should have large joinders ... maybe there shouldn't be a class certification.
Because we remand this case for further proceedings, we leave it to the superior court to reconsider the issue. It will be up to the trial court to determine whether further discovery or an evidentiary hearing is required.
We note that Forestry has raised some concerns that should be addressed in any reconsideration of class certification. According to Forestry, joinder of all who have claims is not impractical: The claims are relatively large, and those who have claims will have to be identified at some point in the litigation.[16] Further, the size of the claims ensures that individual claimants have an adequate incentive to pursue individual claims.[17] In addition, because the plaintiffs' injuries were sustained over the course of a two-week period, there is a possibility that individual issues of causation, damages, and comparative negligence may exist. Forestry has expressed doubt as to whether the class representatives have asserted claims that are "typical" of the class claims,[18] whether there *105 are no conflicts of interest between class members and class representatives,[19] and whether common issues predominate over individual issues.[20] We leave these to the superior court to address on remand.

V. CONCLUSION

For the reasons stated above and in our opinion in Angnabooguk, we AFFIRM the denial of the first motion to dismiss, on Forestry's duty of care, and REVERSE the grant of the second motion to dismiss, on discretionary function immunity.[21] We REMAND the issue of class certification for further consideration by the superior court.

[15]  Alternatively, Rule 23(b) can be satisfied if either of the requirements of Rule 23(b)(1) or (2) is met:

(1) The prosecution of separate actions by or against individual members of the class would create a risk of
(A) Inconsistent or varying adjudications with respect to individual members of the class which would establish incompatible standards of conduct for the party opposing the class, or
(B) Adjudications with respect to individual members of the class which would as a practical matter be dispositive of the interests of the other members not parties to the adjudications or substantially impair or impede their ability to protect their interests; or
(2) The party opposing the class has acted or refused to act on grounds generally applicable to the class, thereby making appropriate final injunctive relief or corresponding declaratory relief with respect to the class as a whole.
[16]  Amenability to jurisdiction should not be an issue. The alleged torts were committed in the state, and the potential claimants have minimum contacts with the state by reason of their interest in the local property that was damaged or destroyed.
[17]  These factors are relevant to the numerosity factor of Rule 23(a)(1) and the superiority factor of 23(b)(3).
