| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to the S&P Municipal Bond Ohio Index (the “Index”) to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the S&P Municipal Bond Index which represents the overall U.S. municipal fixed-income market. The Fund seeks to provide current income by investing in a portfolio of tax-exempt securities so that, normally, distributions of annual interest income are exempt from federal regular income tax and the personal income taxes imposed by the state of Ohio and Ohio municipalities. Top Contributors to Performance Duration management and yield curve positioning contributed positively to relative Fund performance. Specifically, overweight positions in outperforming securities with maturities 12 years and longer had a positive contribution. The Fund held moderate duration short and long positions at different points relative to the Index during a volatile fiscal year which created modest net positive contribution. The 30-year AAA-rated Bloomberg Evaluation Service municipal yield fluctuated over a wide range from 4.59% to 3.34%, ending the period lower by 24 basis points. Credit allocation contributed positively with overweight positions relative to the Index in BBB-, B- and Non-rated securities all of which outperformed the Index. In addition, underweight positions in AAA-rated securities which underperformed the Index also contributed favorably. Sector allocation added to relative performance including underweight exposure to the underperforming Tobacco Settlement Revenue bond sector and overweight exposure to the outperforming Industrial Revenue bond sector. Top Detractors from Performance Security selection had a modest negative contribution to relative performance due to the timing of position adjustments as municipal yields peaked in October 2023. Specifically, the replacement of long duration securities during October with somewhat shorter duration securities mildly diminished returns as municipal yields subsequently declined to finish the calendar year. |

Top Contributors to Performance Yield curve positioning provided a positive contribution to relative performance, particularly due to the Fund’s overweight allocation to bonds with duration greater than eight years. During the reporting period, the Fund’s duration was on average longer than the Index. Thus, the Fund benefitted from falling rates. Credit allocation contributed to relative performance against the Index. Notably, the Fund’s overweight allocation to BBB-rated bonds (which outperformed) and underweight allocation to AA-rated bonds (which underperformed) added to relative performance. Top Detractors from Performance Sector allocation was a net detractor from relative performance. Positions in Local General Obligations, Multi-Family, and Pre-Refunded bonds were a drag on relative performance. These were partially offset by overweight positions in Life Care and Incremental Tax bonds. Individual security selection which reflects factors not explained by duration, yield curve, credit and sector also lagged the Index. The Fund’s emphasis on higher-coupon bonds was a drag on performance versus the Index. |

| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance The following discussion compares the performance of the Fund to a blended index consisting of S&P 25% A and Higher/25% BBB/50% High Yield, All 3-Year Plus Sub-Index (the “Index”) to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the S&P Municipal Bond Index, which represents the overall U.S. municipal fixed-income market. The Fund seeks to provide a high level of current income by investing its assets so that normally at least 80% of the income that it distributes will be exempt from federal regular income tax. Top Contributors to Performance Yield curve management contributed positively to relative performance. An overweight allocation to bonds with durations greater than eight years and a corresponding underweight in bonds with durations between two and six years benefitted from an inverted and steepening yield curve. Credit allocation was a positive factor. An overweight allocation to BB-rated and B-rated bonds benefitted from tightening credit spreads. Security selection contributed favorably as the Fund outperformed the Index after accounting for duration, yield curve, sector allocation and credit allocation contributions. A number of individual holdings that experienced improving credit situations contributed excess returns, notably in the Senior Care sector and various Puerto Rico bonds. During the reporting period, the Fund’s duration averaged 3% longer than the Index, which was a benefit to the Fund with falling rates. Top Detractors from Performance Although sector allocation was slightly positive, an underweight allocation to Higher Education and overweight allocation to Airports were drags on performance. |
