OPINION OF THE COURT
On October 23, 1989, Frank O. Persinger, appellant, was charged by information with nine counts of Bad Checks
1
and
This appeal is from the Order of the Superior Court which affirmed appellant’s judgments of sentence.
We begin by noting that the appropriate standard against which all claims of ineffective assistance of counsel must be measured is well settled.
The threshold inquiry in such claims is whether the issue/argument/tactic which counsel has foregonе and which forms the basis for the assertion of ineffectiveness is of arguable merit; for counsel cannot be considered ineffective for failing to assert a meritless claim. If this threshold is met, it must next be established that the particular course chosen by counsel had no reasonable basis designed to effectuate his client’s interest. Finally, we require that the defendant establish how cоunsel’s commission or omission prejudiced him.
Commonwealth v. Durst,
In determining whether appellant’s claim has arguable merit we must first look to the standard applied in withdraw of guilty plea cases.
When considering a petition to withdraw a guilty plea submitted to a trial court after sentencing, ..., it is well-established that “a showing of prejudice on the order of manifest injustice is required before withdrawal is properly justified.”
Commonwealth v. Shaffer,
Pennsylvania Rules of Criminal Procedure, Rule 319 governing guilty pleas, requires the court to conduct an on-the-record inquiry to determine that the plea is “voluntarily and understanding^ tendered.” Pa.R.Crim.P. 319(a). In order to determine whether the plea is voluntarily and understandingly entered the court must ask questions in six particular areas, including “Is the defendant aware of the permissible range of sentences and/or fines for the offenses charged?” Pa.R.Crim.P. 319 comment. Inquiry into these areas is mandatory,
Commonwealth v. Willis,
... the decision to plead guilty to a charge could not be acceptеd as being knowingly and intelligently entered without an assurance that the accused fully comprehended the maximum punishment that might be imposed for his conduct. This information is obviously an integral part of the knowledge that should be possessed by one who is called upon to make the difficult decision whether to surrender his right to trial and to place himself at the mercy of the sentencing court. No civilized society could tolerate thе waiver of such basic rights from one who was unaware of or misinformed as to such a critical fact.
The record below reveals that, although appellant was informed by the court as tо the permissible range of sentence for each offense, he was not informed that the sentences could be imposed consecutively.

In holding that appellant’s claim was without mеrit, the Superior Court relied upon their decision in
Commonwealth v. Harris,
Appellant has failed to meet the burden of demonstrating manifest injustice in the denial of his motion to withdraw his guilty plea. To grant the motion based only on his assertion that he did not know that his sentences might be imposed consecutively, it seems to us, would permit him to use the withdrawal as a sentence-testing devise.

Significantly, the ABA Standards for Criminal Justice (2nd ed. 1980) relating to Pleas of Guilty provides in relevant part:
(a) The court should not accept a plea of guilty or nolo contendere from a defеndant without first addressing the defendant personally in open court and determining that the defendant understands:
(i) the nature and elements of the offense to which the plea is offered;
(ii) the maximum possible sentence on the charge, including that possible from consecutive sentences, and the mandatory minimum sentence, if any, on the charge, or of any special circumstances affecting probation or release from incarceration;

Our inquiry is not complete, however, until we consider whether counsel had a reasonable basis for his or her course of action designed to serve the best interests of the client. Although there is no record of a hearing at which appellant’s former counsel might have explained the reasons for his failure, we are of the opinion that there could have been no reasonablе basis for counsel’s course of action under these circumstances. Therefore, we conclude that it is not necessary to remand for an evidentiary hearing.
See Commonwealth v. Turner,
For the foregoing reаsons, we hold that defendant’s counsel was ineffective for failure to file a motion to withdraw appellant’s guilty plea, based on the fact that defendant’s guilty plea colloquy was defеctive because he was not informed that the consequences of his guilty plea included the possibility of consecutive sentences. Accordingly, we reverse the order of the Supеrior Court and remand the case for trial.

. Following a hearing on appellant’s Motion for Modification of Sentence, the sentence of one (1) to (2) years imposed for Bad Cheсks at CC8910384 was vacated by reason of merger.
. Appellant acknowledged via the written plea colloquy that he had discussed the permissible range of his sentence with his attorney, howevеr neither defense counsel nor the court explained to appellant that the sentences could result in consecutive terms of imprisonment.
. The Superior Court attempts to distinguish its oрinions in

v.
Fay,
. We note that if counsel had objected to the inadequatе colloquy, the correct maximum sentence would have been explained and the defect corrected. Therefore, counsel's failure to object actually caused the unknowing plea.
