OPINION
The appellant stands convicted of armed robbery. His conviction was upheld by this Court, and the Tennessee Supreme Court denied appellant’s application for permission to appeal. Subsequently, petitioner filed a pro se petition for post-conviction relief and was granted an order by the trial court appointing private counsel to represent the indigent petitioner. On February 14, 1986, after an evidentiary hearing, the trial court entered its findings of fact and conclusions of law denying the petition for post-conviction relief. He now appeals as of right from the judgment of the Criminal Court of Shelby County, raising the issue of ineffective trial counsel. Appellant also asserts that the trial court sua sponte should have granted a new trial.
Specifically, appellant contends that his trial attorney was deficient because he failed to move for a mistrial when his co-defendant obtained a severance and entered a guilty plea during voir dire after eight jurors had been accepted. The record shows, however, that the co-defendant’s severance and change of plea occurred outside the presence of the jury. Moreover, the record shows that the trial court cautioned the eight jurors to draw no inferences or presumptions from the severance.
The right of an accused in a criminal prosecution to the effective assistance of counsel is guaranteed by the Sixth Amendment to the United States Constitution, as well as Article I, § 9 of the Constitution of Tennessee. The United States Supreme Court has stated that the burden of proof of a criminal defendant making an assertion of ineffectiveness is twofold:
(1) He must show that the representation was deficient; and
(2) He must prove that the deficiencies prejudiced the defense, depriving the defendant of a fair trial.

The test in Tennessee to determine the effectiveness of counsel is whether the attorney’s services were “within the range of competence demanded of attorneys in criminal cases.” Baxter v. Rose,
The court in Baxter also adopted the guidelines delineated in United States v. DeCoster,
As a matter of appellate procedure, it is well established that a trial court’s findings upon questions of fact are conclusive unless this Court finds that the evidence preponderates against the lower court’s judgment. Clenny v. State,
As to appellant’s assertion that the trial court sua sponte should have granted a mistrial, such an assertion is meritless for three reasons. First, no error occurred and therefore a mistrial was inappropriate. Secondly, this Court has held that where a co-defendant entered a guilty plea during trial, absent a show of prejudice, the trial court did not err in failing to grant a mistrial sua sponte if proper curative instructions are given. Aldridge v. State,
In essence, appellant has failed to successfully carry the burden of proving the allegation he has pled by a preponderance of the evidence. Weddle v. State,
