There was
a small study (PDF) done on this (79 students) semi-recently, apparently because the idea of formal personal financial training enjoys a certain popularity. The results were actually mixed, and not at all what optimists might have guessed.

Course Impact on Financial Behavior
Table 4 summarizes responses to questions relating to financial behavior based on whether or not the respondent had taken the personal financial management course.
The results show that the course in personal financial management did not systematically impact respondent’s financial behavior. Those who had the course were more likely to make credit card payments on time (71.8% vs. 67.5%); however they were also less likely to pay their credit card in full each month (53.8% vs. 60.0%). Therefore, respondents taking the course were more likely to pay interest on their credit card balance.
Also, while a greater proportion of those taking the course balanced their checkbook (46.2% vs. 32.5%),
they also were more likely to have bounced a check (35.3% vs. 26.3%). In addition, those who had not taken the
course were more likely to prepare their own taxes (35.0% vs. 33.3%) and believed that they had adequate savings and investments (55.0% vs. 43.6%). To estimate overall financial behavior, we assigned a point for each reported beneficial financial behavior. The mean number of points accumulated by all respondents was 3.54, indicating that respondents reported favorable financial behavior on about half of the seven items. Although those who had taken the personal financial management course had a slightly higher mean score than did those who had not (3.62 and 3.47), the difference was not significant at the .05 level (see Table 4).
