The opinion
SINGLETON, Judge,
dissenting.
The primary responsibility for determining an appropriate sentence in criminal cases rests with the trial court. State v. Graybill, 695 P.2d 725, 729 (Alaska 1985). Our sentence review authority is limited. We are to determine an appropriate sentencing range for a given offense and offender, and then compare the sentence being reviewed to determine whether it falls within that range. See, e.g., McClain v. State, 519 P.2d 811, 813 (Alaska 1974). 1 If *1018 it falls within the appropriate range, we must approve the sentence. It is only where the sentence being reviewed is outside the appropriate range that remand for resentencing is appropriate. In State v. Andrews, 707 P.2d 900, 912-13 (Alaska App.1985), affirmed, 723 P.2d 85 (Alaska 1986), we recognized a sentencing range for first offenders convicted of aggravated offenses of sexual abuse or sexual assault on minors of between ten and fifteen years of unsuspended incarceration. See also Covington v. State, 747 P.2d 550, 553 (Alaska App.1987). The majority accepts the trial court’s conclusion that this is an aggravated case because of the victim’s age and the injuries she suffered. I agree that the trial court’s conclusions along this line are not clearly mistaken. Consequently, it would appear that the sentence imposed, twenty years with five years suspended, is within the previously recognized range of sentences and should be approved. 2 The majority’s conclusion that the appropriate sentence is fifteen years with three years suspended ignores our past decisions and exceeds our sentence review authority. It amounts to the kind of tinkering with trial court sentences forbidden by State v. Chaney, 477 P.2d 441 , 444 n. 12 (Alaska 1970).
I therefore dissent.
. In McClain , the court evaluated two lines of authority purporting to describe the test which an appellate court should apply in reviewing trial court sentencing decisions — cases adopting a zone of reasonableness test, and cases utilizing a clearly mistaken test. The court concluded that both tests meant the same thing:
Implementation of these two formulations reveals a similar analytical framework which *1018 accounts for their combined use in some cases. Analytically, the clearly mistaken test implies a permissible range of reasonable sentences which a reviewing court, after an independent review of the record, will not modify. The zone of reasonableness merely describes that range of reasonable sentences which after an independent review of the record will not be modified by the reviewing court.

Since the two tests were identical, the court sought to avoid future semantic confusion by henceforth referring to the test as the "clearly mistaken" test. Id. at 813-14 .
. In reviewing sentences, primary attention must be given to unsuspended time. Graybill, 695 P.2d at 730-31 .
