Defendant Neal Winter was convicted of one count of sexual assault in violation of -13 V.S.A. § 3252(a)(1)(A). He now appeals, raising the single issue that evidence that he committed a sexual assault on another woman, over four years prior to the charged incident, was improperly admitted. We agree and reverse and remand for a new trial.
The incidents for which defendant was charged occurred on two nights in November 1991. Defendant was employed at a group home in Bennington and often was the sole staff person present overnight. The group home, which housed six persons, was run by a local mental health agency as a temporary treatment facility for patients with mental illness or substance abuse problems.
*390 In November 1991, the victim in this case was thirty-two years old, and had entered the group home to serve a house arrest sentence for a DUI conviction. She testified that defendant, whom she had known in passing, began making unwelcome sexual remarks to her. She described the following incidents.
On the first night, defendant entered her bedroom while she was asleep, knelt by her bed and fondled her breast. She awoke and called him a name, whereupon he left. Two nights later, the victim awoke to find defendant performing oral sex on her. Thereafter, he overpowered her and compelled her to have intercourse with him. He warned her against disclosing what occurred, stating that no one would believe her, and threatening to kill her if she talked.
The State charged defendant with lewd and lascivious conduct for the events of the first night and two counts of sexual assault, one involving the oral sex and the other the intercourse, for the events of the second night. At trial, the State called the victim and other residents and staff of the home, who corroborated various details of the victim’s account. In the investigation of the claims, defendant denied having had sex with the victim. At trial, however, defendant testified that he did have sex with the victim, but that it was consensual.
Defendant was found guilty of one count of sexual assault, the count charging him with committing nonconsensual oral sex on the second night. After the court imposed a sentence of four to ten years, defendant appealed.
The evidence involved in this appeal was that in August 1987, when defendant was living in New York state, he sexually assaulted his children’s seventeen-year-old babysitter, S.M., on numerous occasions in his home. Although the assaults began by forced vaginal intercourse, on later occasions defendant began with oral sex. S.M. reported the sexual assaults, and they were investigated by the New York police. Defendant stated that he had sex with S.M. on one occasion and that it was consensual.
The State gave notice that this evidence would be introduced through the testimony of S.M., and defendant filed a motion in limine to exclude the evidence. Based on the memoranda of the parties, and without a hearing, the trial court denied the motion. It found the evidence admissible to show motive and a common scheme, but not to show a plan. Holding that admissibility turned on similarity between the former incident and the incident for which defendant is charged, as well as proximity in time, the court found the requisite similarity *391 and proximity. The court found six similarities: (1) a power differential — the employer/employee relationship with S.M., the relationship of a “prison guard” to the victim; (2) sexual comments as a manner of approach; (3) initial contact with the woman’s breasts; (4) the use of physical force to complete the sex acts; (5) oral contact to facilitate intercourse; and (6) a claim of consent as a “cover-up.” It concluded that the passage of four years did not render the S.M. incident too remote. The court also balanced probative value against prejudicial effect and found probative value controlled because the State had a need for the testimony to deal with the credibility problem caused by a victim who “was a resident of a group home for the mentally ill.” S.M. testified at the trial. In its instructions, the court explained the limited use that the jury could make of S.M.’s testimony and informed the jury that the testimony could not be considered for propensity purposes. The instructions authorized the jury to consider the evidence only if it showed motive or common scheme. The court defined these authorized purposes:
As to motive, it is not an essential element of the state’s case that it . . . prove that the defendant had a specific goal or motivation or reason to commit these acts alleged. However, whether or not a person had a motive or reason for the doing of an act is proper for your consideration in determining if in fact the person did the act in question, and also in determining the manner that the act in question may have occurred.
As to common scheme, what this refers to is that if it is claimed that a person on the occasion in question did certain acts in a particular manner, and there is evidence that on a prior occasion that person did similar acts in a similar manner, then one could infer or conclude that it is more likely that the acts in question did occur in the manner alleged.
The court went on to charge the jury that it should look at similarity and proximity in time in determining the weight to be assigned S.M.’s testimony.
The question before us involves the application of V.R.E. 404(b), which provides:
(b) Other crimes, wrongs, or acts. Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show that he acted in conformity therewith. It may, however, be admissible for other purposes, such as proof of *392 motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.
The rule excludes “bad act” evidence “introduced for the purpose of showing a general propensity to commit the acts in question.”
State v. Bruyette,
Although Rule 404(b) is most often invoked in cases in which the defendant is charged with a sexual misconduct crime, we have not carved out a special propensity rule for such crimes as an exception to Rule 404(b). Thus neither before the adoption of the Vermont Rules of Evidence, nor since, have we allowed the admission of acts of sexual misconduct to show a lustful disposition.
1
Even if we had created such a rule in the past, it would now clearly be inconsistent with Rule 404(b). See
Getz v. State,
Just as we have no special exception to Rule 404(b) for sexual misconduct cases, neither have we adopted special, more liberal, interpretations of Rule 404(b) to allow the admission of prior bad act evidence in such cases, especially when we would not admit similar evidence in other cases. Cf.
State v. Hurley,
The closest we have come to a special rule for prior bad act evidence in sexual misconduct cases is when, in a prosecution for sexual abuse of a child on a particular occasion, the State has been allowed to show that the act charged is only one of a continuous series of acts. See
State v. Forbes,
The point of establishing the existence of an incestuous relationship was not to make an issue of defendant’s general character for sexually abusing females of minor age. Rather, the point was to establish specifically defendant’s propensity to engage in sexual contact with his daughter as an object of his desire.

We must also emphasize that the grounds for admission specified in Rule 404(b) are not magic words, the utterance of which automatically admits all uncharged misconduct evidence. The State has the burden to show precisely how the proffered evidence is relevant to the theory advanced, how the issue to which it is addressed is related to the disputed elements in the case, and how the probative value of the evidence is not substantially outweighed by its prejudicial effect. See
People v. Golochowicz,
*394 Recognizing that it could not admit S.M.’s testimony on propensity grounds, the trial court relied on two nonpropensity grounds, motive and common scheme. We conclude that neither applies in this case. 2
The clearest example of using a prior crime to establish motive is when the victim knows that the defendant committed the prior crime and the defendant kills the victim to prevent disclosure. We have used similar logic in sexual assault cases. For example, in
State v. Recor,
We liberally allowed bad act evidence bearing on motive in
State v. Jones,
In this case, however, there is no connection between the alleged assault on S.M. and the assault on the victim that explains why the latter occurred as alleged. Indeed, the logic the jury was invited to use was that because defendant was motivated by a desire
*395
for sexual gratification in assaulting S.M., it was more probable that he was similarly motivated in assaulting the victim in this case. As such, this is no more than an impermissible propensity analysis. See
State v. Saltarelli,
We also cannot accept the alternative rationale advanced by the trial court that the uncharged misconduct evidence is relevant to show a common scheme. Rule 404(b) does not mention this rationale as grounds for admission, although this phrase has been used in some of our cases, see, e.g.,
State v. Chenette,
The use of uncharged misconduct evidence to show a plan is described in detail in
State v. Catsam,
Evidence that the defendant previously molested the victim, and threatened her with harm if she were to reveal the incident, gives rise to the legitimate inference that because of the manner in which the prior sexual acts were perpetrated, the prior acts and the charged crime were part of a concerted scheme or plan of molestation. If the evidence of prior acts establishes the existence of such a plan, the necessary connection between the prior *396 acts and the crime charged is present, bringing the evidence within the scope of Rule 404(b).
Id.
at 381,
Our acknowledgement of the danger of admitting uncharged misconduct evidence to show a plan demonstrates an understanding that cases like
Catsam
can cause courts to stretch traditional logical constraints. See, e.g.,
State v. Brooks,
The trial court here recognized the difficulty of drawing the inference of the existence of a plan from the S.M. evidence and attempted to evade the Catsam holding by finding that the S.M. events were too remote in time to show a plan, but that instead they showed a “common scheme.” Even if we thought that there was some distinction between a scheme and a plan such that temporal proximity is unnecessary for a scheme, we cannot so easily eviscerate the Catsam requirements without crossing the “perilously close” line to propensity evidence.
Catsam
clearly holds that temporal proximity is a prerequisite to admission in plan or scheme cases.
Id.
Thus, we have followed the majority of states in rejecting the notion that temporal remoteness goes only to the weight of the evidence, not its admissibility. Compare
State v. Jones,
*397
We have not adopted hard-and-fast time limits; we believe that the necessary proximity must vary with the circumstances. For example, in
State v. Hurley,
the defendant was charged with sexually assaulting his nephew, and we held that evidence that he had sexually assaulted cousins of the victim some ten to twelve years before the charged incident was too remote to be admitted.
The precise amount of elapsed time is less important than the relation between the passage of time and the inference that there is an overall plan to the defendant’s actions. Thus, in child sexual assault cases, we see no difficulty in admitting evidence of much earlier assaults on the victim when the evidence also shows such assaults have continued right up to the charged event. See
Ashley,
In this case, the State’s theory that defendant had a plan or common scheme linking his assault on S.M. to his assault on the victim here founders upon the passage of over four years between the two assaults. Indeed, in the intervening four years, defendant moved from New York to Vermont and apparently had started a new life. There is no evidence of acts of sexual misconduct between the events,
3
nor a showing of lack of opportunity. In similar circumstances, other courts have found the uncharged misconduct evidence too remote. See
State v. Miller,
The real import of the trial court’s distinction between a common scheme and a plan appears to be in its view that the uncharged misconduct and the charged conduct were so similar that evidence of the uncharged misconduct could be admitted to show a common scheme despite its temporal remoteness.

Although modus operandi is normally used to show identity, see Imwinkelried, Uncharged Misconduct Evidence,
supra,
§ 3:10, at 3-21, some courts have held that a showing of modus operandi can go to other issues in the case. Indeed, some courts have held that modus operandi evidence is admissible when the issue in dispute is whether the victim consented to the sexual activity. See
State v. Plaster,
In modus operandi cases, the ‘“pattern and characteristics’ of the prior acts must be so distinctive, in effect, to constitute the defendant’s signature.”
Bruyette,
We agree with the trial court that there are enough similarities to meet the
Catsam
test. See
We would also give particular weight to connections between events. For example, the State responds to the difference in setting and victim age by arguing that in each case defendant was in a position of power over the victim. That argument would better support the State’s theory if the State had showed that defendant reached a position of power that then enabled him to have sexual relations with women. There was no such showing here.
We conclude that the evidence of the sexual assault on S.M. was not admissible to show either motive or common scheme. Accordingly, its admission violated Rule 404(b).
As noted earlier, assuming that the proffered evidence meets the requirements of Rule 404(b), the evidence must also pass the Rule 403 balancing test, in which the probative value of the evidence is compared to any unfair prejudicial effect. That balancing is highly discretionary. See
Parker,
As we have expressed in other decisions, the potential unfair prejudice to the defendant is great from evidence of a past unpunished crime that is similar to that for which he is charged. See
Forbes,
In cases in which such high potential for prejudice exists, we have often noted a related high probative value. See
Bruyette,
The trial court emphasized the need for the evidence because of the victim’s situation. We agree that the State’s need for the evidence is a major factor in the balancing process. See
Catsam,
There is a final factor that was not considered by the trial court — -that is, how definitely the State has proved defendant’s commission of the uncharged misconduct. See Imwinkelried, Uncharged Misconduct Evidence, supra, at § 8.04, at 8-10 to -11. The record indicates that S.M. reported to the police her allegation of defendant’s sexual assaults upon her, but he was not criminally charged for them. Defendant was charged with providing alcoholic beverages to S.M., who was then a minor.
We have adopted the rule of
Huddleston v. United States,
*401
Our adoption of a low threshold for admission requires the trial court to look at the strength of the proof of the uncharged misconduct evidence in balancing under Rule 403. We have expressed concern about the use of uncharged misconduct evidence when the record shows that there was an official investigation of the allegation and “insufficient evidence was found to pursue it.”
McCarthy,
The State has not claimed that the admission of the testimony of S.M. was harmless. In view of the jury’s split verdict, we cannot say it was harmless.
Reversed and remanded.
Notes
One author argues that this Court followed a lustful disposition rule at common law in statutory rape cases, and has generally adopted a lustful disposition exception since enactment of Rule 404(b). See Reed,
Reading Gaol Revisited: Admission of Uncharged Misconduct Evidence in Sex Offender Cases,
21 Am. J. Crim. L. 127, 170 & n.238, 188 n.340 (1993). His argument that we followed such a rule at common law is based on a two sentence discussion in
State v. Willett,
His argument with respect to our post-Rule 404(b) jurisprudence is based entirely on
State v. Cardinal,
The State has not asked us to examine other possible grounds for admission, and we have not done so. We believe a shift of grounds would be particularly inappropriate in this case in which the trial court carefully explained to the jury the permissible uses of the uncharged misconduct evidence, and we have concluded each of those uses was in error.
The State originally noticed that it intended to show that defendant sexually abused H.D., a sixteen-year-old friend of S.M., at his home also in August 1987. This evidence was not offered at trial.
In view of our analysis, we need not decide whether temporal remoteness defeats the -use of modus operandi to admit uncharged misconduct evidence. Cf. Imwinkelried, Uncharged Misconduct Evidence, supra, § 3:11, at 3-23 to -24 (in determining whether requisite showing of high degree of similarity between charged and uncharged crimes made to demonstrate modus operandi, courts normally consider three factors: temporal, and to lesser degree, geographic proximity, and resemblance of methodologies).
