OPINION OF THE COURT
This appeal presents the question whether, in a criminal case, reversal is required when a district court fails to conduct a colloquy with a defendant before accepting a written waiver of her right to a jury trial. We conclude that under the circumstances present here reversal is neither mandatory nor appropriate, and therefore affirm the conviction.
A.
Ruth Anderson, the defendant, was indicted on two counts of wilful and intentional tax evasion. Anderson signed a form waiving her right to a trial by jury, to which the government and the district court agreed in writing. Following a bench trial, she was convicted on both counts. Her primary contention on this appeal is that the district judge committed reversible error by failing to conduct a colloquy with her on the record before accepting the written waiver of a jury trial. She acknowledges that there is no rule now in force in this Circuit requiring such a procedure, but requests that this Court adopt a supervisory rule applicable to this as well as subsequent cases, which would require the district courts in this Circuit to conduct a colloquy in all criminal cases where the defendant seeks to waive the right to trial by jury.
B.
The right of a criminal defendant to be tried by a jury of her peers is a fundamental constitutional guarantee.
Duncan v. Louisiana,
A right to jury trial is granted to criminal defendants in order to prevent oppression by the Government.... Beyond this, the jury trial provisions in the Federal and State Constitutions reflect a fundamental decision about the exercise of official power — a reluctance to entrust plenary powers over the life and liberty of the citizen to one judge or to a group of judges. Fear of unchecked power, so typical of our State and Federal Governments in other respect, found expression in the criminal law in this insistence upon community participation in the determination of guilt or innocence.
Duncan,
Rule 23(a) of the Federal Rules of Criminal Procedure requires that the right to jury trial be waived explicitly in writing; no reference is made to oral colloquys. Nonetheless in addition to the written waiver referred to in Rule 23(a), a district court usually conducts a colloquy with the defendant, on the record, to ascertain whether the defendant fully understands the nature

of the right being relinquished and the implications of that decision. As we stated in
United States v. Mitchell,
Although this is the preferred practice, we decline to follow the Seventh Circuit and set forth a supervisory rule making it the required procedure in this Circuit.
See United States
v.
Delgado,
C.
The defendant in this case has raised two additional challenges to her conviction. She maintains first that her waiver of a jury trial was not in fact made knowingly and intelligently because her attorney never explained to her the implications of the waiver form that she signed. Anderson, who was employed as a bookkeeper, has had three years of college education, taking night classes at the University of Pittsburgh. The district court, after observing her demeanor throughout the trial, found her to be “an intelligent and a cultured woman, alert and perceptive.” Although Anderson’s attorney, an experienced and able member of the bar, could not recall whether he explained the waiver to her, he made it clear that his practice was to discuss with defendants whom he represented the implications of the decision to proceed without a jury. In addition, the Assistant United States Attorney assigned to the case testified that she had been told by Anderson’s lawyer that he had discussed the waiver with Anderson, and that Anderson had decided that “she’ll be better off with one person deciding her fate as opposed to twelve people deciding her fate.” Appx. at 96a. On the basis of all these facts, we conclude that the district court did not err in finding Anderson’s waiver to be knowing and intelligent.
Anderson’s final argument is that the evidence presented at trial was insufficient to prove beyond a reasonable doubt that she intentionally committed the crimes with which'she was charged. After a thorough review of the record of the trial, we conclude that this claim is without legal merit.
The judgment of the district court,
