OPINION
RILEY, Judge.STATEMENT OF THE CASE
Appellant-Petitioner, Brian E. Mast (Mast), appeals the post-conviction court's denial of his Petition for Post-Convietion Relief.
We reverse and remand.
ISSUE
Mast raises three issues on appeal, one of which we find dispositive and which we restate as: Whether Mast received ineffective assistance of trial counsel.
FACTS AND PROCEDURAL HISTORY
On January 26, 1989, the State charged Mast with Count I, rape, as a Class A felony, Ind.Code § 35-42-44; Count II, criminal deviate conduct, as a Class A felony, I.C. § 35-42-4-2(1); Count III, burglary, as a Class A felony, 1.C. § 35-48-2-1; and Count IV, battery, as a Class C felony, .C. § 385-42-2-1. On June 1, 1989, Mast's initial trial counsel filed a Notice of Defense of Mental Disease or Defect and a Motion to Suppress Statements. A hearing on those two motions was set for later that month. On June 27, 1989, pursuant to Indiana Code section 35 36-3-1, the trial court appointed Doctors John Rathbun (Dr. Rathbun) and Herbert Trier (Dr. Trier) to examine and evaluate Mast as to his competency to stand trial and to his sanity at the time of the alleged offenses. On July 25, 1989, Dr. Rathbun sent an evaluation to the trial court, which was filed on August 3, 1989. Dr. Rathbun elaborated in his letter that when he interviewed Mast, Mast was brought to the examination shackled in a padded one-piece garment. Dr. Rathbun concluded that while Mast did not "show depressed affect, express delusional thinking or appear to be hallucinating," due to muscular rigidity Mast exhibited during the interview, Dr. Rathbun was nevertheless unable to form a definite opinion regarding Mast's competency to stand trial (Appellant's App. Vol. II, p. 97). He also stated that repeated interviews would be necessary to establish his mental condition and suggested that Mast be incarcerated in a maximum security forensic psychiatry unit to be evaluated by physicians 24 hours a day.
On July 31, 1989, Mast planned to enter a plea agreement with the State. Howeyver, during the hearing, Mast claimed not to remember the facts surrounding the event and withdrew the agreement.1 However, four days later on August 3, 1989, Mast, while represented by a substitute counsel,2 *854pled guilty pursuant to the terms of the previous plea agreement. It is not clear from the record whether Dr. Rathbun's report, which was mailed July 25, 1989, but filed by the clerk on August 3, 1989, was before the trial court during the plea agreement.
On August 7, 1989, Dr. Trier sent the trial court an evaluation, stating he had examined Mast and concluded:
Although this man does not present a classical case of psychosis his thinking can at time[s] be so chaotic although his behavior apparently is under control. His behavior problems have existed for so long that I doubt that he has the ability to meaningfully help in his defense or understand thoroughly the nature of the charges against him.
(Appellant's App. Vol. II, p. 100). Dr. Trier also commented that Mast had a bandage on his right arm due to the fact that he "bit out the flesh" on his arm and the taping was necessary to keep him from doing it again. (Appellant's App. Vol. II, p. 100). Mast also had "residual scarring" likely from "prior suicidal attempts." (Appellant's App. Vol. II, p. 100). Dr. Trier's evaluation was addressed to the wrong trial judge and did not arrive before the plea hearing. Additionally, the evaluation was dated August 7, 1989, and would not have arrived in time for the guilty plea hearing which took place on August 3, 1989.
On August 28, 1989, the trial court sentenced Mast pursuant to the plea agreement, which provided that Mast would be sentenced to concurrent terms of thirty years on Counts I and II, and five years consecutively on Count IV, resulting in an aggregate term of thirty years imprisonment.
On November 27, 1990, Mast filed a pro se Petition for Post-Conviction Relief. On August 4, 1994, Mast, with counsel, moved to withdraw his petition without prejudice. On October 15, 2001, Mast filed a second pro se petition which was amended by counsel on November 27, 2006. On April 283, 2008, a post-conviction hearing was held. During the post-conviction hearing, the post-conviction court asked whether Dr. Rathbun's report had been received by the trial court:
[PCR COURT]: I want to just-And I know this was a long time ago, [counsel], but going back to the July 31st hearing, Mr. Mast does not ask you about the mental health reports coming back and you say at that time something has come back or yes to the question.
[TRIAL COUNSEL]: Okay. He says, "I was-I-I'll sign it. Did the reports come back from my mental health yet?" and I said "Yes."
[PCR COURT]: So you must have had at least one of the reports back by then or you would not have answered in the affirmative, would you?
[TRIAL COUNSEL]: No. I must have had something back.
(Tr. pp. 56-57). However, later on in the transcript of the post-conviction hearing, it was noted that the report was not actually file stamped by the trial court until August 3, 1989. When asked by the post conviection court whether the initial trial counsel received any discovery after April 11, 1989, he stated:
No. I don't-I don't know. I do know that it-I would have received anything [the State] had; and basically, this document has a file mark of August 3rd on it
(Tr. p. 61). On September 18, 2008, the post-conviction court issued Findings of *855Fact and Conclusions of Law denying Mast's Petition for Post-Conviction Relief. (1984), reh'g denied. The defendant must prove (1) his or her counsel's performance fell below an objective standard of reasonableness based on prevailing professional norms, and (2) there is a reasonable probability that, but for counsel's failure to meet prevailing professional norms, the result of the proceeding would have been different. Johnson v. State, 832 N.E.2d 985, 996 (Ind.Ct.App.2005), reh'g denied, trans. denied (citing Strickland, 466 U.S. at 690, 104 S.Ct. 2052). Essentially, the defendant must show that counsel was deficient in his or her performance and the deficiency resulted in prejudice. Johnson, 832 N.E.2d at 1006. Because all criminal defense attorneys will not agree on the most effective way to represent a client, "isolated mistakes, poor strategy, inexperience, and instances of bad judgment do not necessarily render representation ineffective." Bieghler v. State, 690 N.E.2d 188, 199 (Ind.1997), reh'g denied, cert. denied, 525 U.S. 1021, 119 S.Ct. 550, 142 L.Ed.2d 457 (1998). Thus, there is a strong presumption that counsel rendered adequate assistance and used reasonable professional Judgment. Timberlake v. State, 753 N.E.2d 591, 603 (Ind.2001). If it is easier to dispose of an ineffectiveness claim on the ground of lack of sufficient prejudice, that course should be followed. Id.
Under the first Strickland prong, Mast argues that his trial counsel should have awaited the results of the psychiatrists evaluations and requested a competency hearing pursuant to I.C. § 35-36-31 3 to
Mast now appeals. Additional facts will be provided as necessary.
DISCUSSION AND DECISION
I. Standard of Review
Under the rules of post-conviction relief, the petitioner must establish the grounds for relief by a preponderance of the evidence. Ind. Post-Conviction Rule 1 § 5. To succeed on an appeal from the denial of relief, the post-conviction petitioner must show that the evidence is without conflict and leads unerringly and unmistakably to a conclusion opposite to that reached by the post-conviction court. Strowmatt v. State, 779 N.E.2d 971, 975 (Ind.Ct.App.2002).
II. Effective Assistance of Counsel
Mast argues that the post-conviction court should be reversed because he received ineffective assistance of counsel. Specifically, he contends that his trial counsel rendered ineffective assistance because he was advised to enter into a guilty plea and guided through a sentencing hearing without awaiting the results of the competency evaluations.
To establish a violation of the right to effective counsel as guaranteed by the Sixth Amendment, petitioners typically must establish both prongs of the test set forth in Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 *856establish his mental competency before guiding him through the guilty plea In response, the State claims that Mast's trial counsel was in the best position to determine whether Mast was competent to proceed with the guilty plea.
A defendant is not competent to stand trial when he is unable to understand the proceedings and assist in the preparation of his defense. I.C. § 35-36-3-1. The right to a competency hearing pursuant to Indiana Code § 35-36-3-1 is not absolute. Campbell v. State, 732 N.E.2d 197, 202 (Ind.Ct.App.2000). Such a hearing is required only when a trial judge is confronted with evidence creating a reasonable or bona fide doubt as to a defendant's competency, which is defined as whether a defendant currently possesses the ability to consult rationally with counsel and factually comprehend the proceedings against him. Id. The presence of indicators sufficient to require the court to conduct a hearing under I.C. § 35-36-3-1 must be determined upon the facts of each case. Hadley v. State, 496 N.E.2d 67, 71 (Ind.1986). Whether reasonable grounds exist to order evaluation of competency is a decision that will be reversed only if we find that the trial court abused its discretion. Id. A trial judge's observations of a defendant in court are an adequate basis for determining whether a competency hearing is necessary; such a determination will not be lightly disturbed. Id.
In Matheney v. State, 688 N.E.2d 883, 899 (Ind.1997), the defendant filed a notice of insanity defense and requested a psychological evaluation to determine his competency to stand trial. Both psychiatrists found the defendant to be competent to stand trial. Id. As a result, the defendant's trial counsel did not request a competency hearing. Id. Our supreme court held that given the psychiatrists' determination before trial, the defendant's trial counsel was not ineffective for failing to follow up their request for a competency hearing. Id.
In this case, Mast's trial counsel put the trial court on notice that Mast's mental health might be at issue when he filed a Notice of Mental Disease or Defect. Specifically, during the post-conviction hearing, which was held twenty years after Mast pled guilty making it difficult for parties to recall events, Mast's trial counsel testified that although he would not permit a client to plead guilty if he did not "feel that it was in their best interests and that they were indeed guilty," he also could not "testify today about what Brian Mast's level of competency was at the time from independent recollection." (Tr. pp. 40, 41). However, he later testified at the post-conviction hearing that he must have had some question about Mast's mental capacity because he filed a Notice of Mental Disease or Defect. He testified "... [I] must have had a question. I don't routinely file those. I must have had a question about his competency." (Tr. p. 54).
The trial court responded to Mast's trial counsel's request by appointing Dr. Rath-bun and Dr. Trier to evaluate Mast's mental capacity. Dr. Rathbun's evaluation, which may have never even reached the trial court stated:
Mr. Mast was brought to the examination shackled in a padded one-piece garment. He has numerous old self-inflict*857ed slash marks on the inside of his left arm and a four inch by one and a half inch tear through the dermis on his right arm which he stated was self-inflicted by biting.... He then manifests the appearance of an oculogyric crisis, which is a fairly severe condition of muscular rigidity that occurs in people who have been given neuroleptic medication.
{Appellant's App. Vol. I, p. 96). While the report also indicated that Mast had a long history of "self-directed violence, which appears manipulatively directed to avoiding the consequences of his bad behavior," the report concluded that a definite opinion regarding the individual's competency to stand trial or his sanity at the time of the incident could not be formed. (Appellant's App Vol. I, p. 97). Rather, Dr. Rathbun determined that more tests were needed to establish Mast's mental condition.
Dr. Trier's report, which was sent to the wrong trial judge siz days after the guilty plea agreement, stated that "[the facts concerning the charges that he faces he recalls in a somewhat distorted manner and he may or may not be able to interpret these facts accurately." (Appellant's App. Vol. II, p. 100). Ultimately, Dr. Trier's report concluded that Mast's "behavior problems have existed for so long that I doubt that he has the ability to meaningfully help in his defense or understand the nature of his charges." (Appellant's App. Vol. II, p. 100).
Unlike Matheney, where the results of the psychiatrists' evaluations concluded that the defendant was competent to stand trial and thus a competency hearing was unnecessary, in this case, one report stated that Mast was not competent to stand trial and the other report could not make a determination one way or another. Ultimately, it was the responsibility of the trial counsel to ensure that the psychiatrists reports were given to the court and a competency hearing was requested. Mast's trial counsel testified at the post-conviction hearing that he hesitated about Mast's competency but nevertheless, proceeded with a guilty plea without awaiting the results of the psychiatrists.
Under the second prong, Mast contends that if the ease had proceeded to a competency hearing, the court would have had the psychiatrists' reports and would have been aware of the inconclusive nature of Dr. Rathbun's report and Dr. Trier's determination that Mast was likely unable to understand the nature of the charges against him. But for Mast's counsel's error, the result of the proceeding might have led to Mast's commitment to a mental institution with a re-evaluation instead of a guilty plea.
Based on the facts before us, we find that Mast's trial counsel fell below objective standard of reasonableness by not waiting for the results of the evaluations when one report suggested more evaluations were needed and the other report questioned Mast's ability to understand the proceedings. Additionally, there is a reasonable probability that the outcome of the case would have been different had the trial court been aware of the psychiatrists reports.
CONCLUSION
Based on the foregoing, we conclude that Mast's counsel rendered ineffective assistance by allowing his client to enter into a guilty plea without awaiting the results of his mental evaluation.
Reversed and remanded.
BAKER, C.J., concurs with separate opinion. FRIEDLANDER, J., dissents with separate opinion.. The following is the conversation from the July 31, 1989 guilty plea hearing:
[TRIAL COURT]: What is it that makes you guilty of that [rape]?
[MAST]: Rape. That's all
[TRIAL COURT]: What did you do?
[MAST]: I raped her.
[TRIAL COURT]: Okay. Give me a little more detail?
[MAST]: That's all.
[TRIAL COURT]: Okay. And how did you
go about this rape?
[MAST]: I don't remember, Your Honor. I don't
[TRIAL COURT]: Did you use force?
[MAST]: Withdraw, I withdraw it. I'm sorry. I can't. I don't remember anything after I hit her. That's all, that's all I remember....
[MAST]}: I withdraw my plea bargain. Take me downstairs. I want a jury trial. (Petitioner's Ex, D, p. 6).
. Mast's initial trial counsel was not with Mast when he entered into the plea agreement. Instead, another attorney with the Allen County Public Defender's office appeared *854with Mast and entered a written appearance on August 8, 1989.
. LC § 35-36-3-1 provides as follows:
(a) If at any time before the final submission of any criminal case to the court or the jury trying the case, the court has reasonable grounds for believing that the defendant lacks the ability to understand the proceedings and assist in the preparation of his defense, the court shall immediately fix a time for a hearing to determine whether the defendant has that ability. The court shall appoint two (2) competent, disinterested psychiatrists, who shall examine the defendant and testify at the hearing as to whether he can understand the proceedings and assist in the preparation of his defense. (b) At the hearing, other evidence relevant to whether the defendant has the ability to understand the proceedings and assist in the preparation of his defense may be introduced. If the court finds that the defendant *856has the ability to understand the proceedings and assist in the preparation of his defense, the trial shall proceed. If the court finds that the defendant lacks this ability, it shall delay or continue the trial and order the defendant committed to the department of mental health, to be confined by the department in an appropriate psychiatric institution.
