Student transportation funding in Idaho falls mainly under Idaho Code §33-1006, with some portions being specified under Chapter 15 Title 33 and Idaho Code §33-5207 regarding charter school advanced payment.

Student transportation funding is further detailed in the IDAPA 08.02.02.150, and the reimbursement matrices available on the Idaho Department of Education Student Transportation website.

Due to the information required to calculate funding under Idaho Code, payments to school districts and charter schools are made on a prior year reimbursement basis. Because of this, the funding formula which will begin payments in February of the current fiscal year, reflects transportation expenses for the prior fiscal year. As we move along throughout the fiscal year, the final reimbursement amount is subject to modification as it changes with the effects caused by other claims being audited.

School districts and charter schools have the option of running a district-owned transportation program or a contracted program. Furthermore, there is also the in-lieu option only in which a set rate (Idaho Code §33-1503) is paid to parents or guardians to transport their children.

Not all transportation related-expenses are claimed or reported to the Idaho Department of Education as part of the reimbursement process. For example, unapproved capital expenses, indirect staff costs, and legal fees are not eligible for reimbursement.

Transportation of students in vehicles other than a conforming “yellow” bus or authorized vehicles inventoried through the online Idaho Bus Utilization System (IBUS) also falls under this category. Costs associated with this transportation are not included in the reimbursement formula. However, most contracted “yellow” buses are inventoried under the vendor and would be eligible.  Ensure that any authorized vehicle mileage logs are available during your reimbursement claim. 

The use of district or charter school cars and vans, as well as district or charter school-owned buses that are not approved alternative vehicles with the Idaho Department of Education, are not eligible to be claimed as part of the reimbursement process.

Unlike claimable expenses, there are non-reimbursable items which are still claimed because the funding formula will remove these expenses as part of its calculation. For example, such non-reimbursable items are wages for activity drivers and fuel for activity mileage, as all other miles including extra-curricular and field trip miles, are non-reimbursable.

Idaho Code §33-1006(1) and Idaho Code §33-1501 require that the only miles which may be reimbursed are “those directly associated with the transporting of students for the purposes of regular school attendance during regular days and hours”. This is further divided in SISBO and the Idaho Department of Education’s reimbursement matrices and claim instructions. The four reimbursable mileage categories are:

• Regular To/From School (R) – Claimable miles while transporting students to and from school, including year-round schools.
• Unique To/From School (R) – Claimable miles while transporting students to and from special school programs under Idaho Reading Indicator (IRI) and other eligible programs.
• Shuttle Trips (R) – Claimable miles while transporting students on regularly recurring days for educational programs during regular school days and hours.
• Summer Programs (R) – Claimable miles while transporting students to and from school for IRI, Extended School Year (ESY), and summer migrant education programs (regular summer school miles for non-year-round schools are non-reimbursable).
• Field Trips (R) – Claimable mileage for school activities that are part of the total education program in line with content standards as well visits to colleges and universities.
• Maintenance (R) – Claimable mileage for moving the “yellow school bus” to facilities for repairs/maintenance, test driving, etc.
• Training (R) – Claimable mileage incurred for new and existing drivers’ behind the-wheel and in-service training.

Additionally, Idaho Code §33-1501 limits To/From School miles to those between school and the student residence or a day care facility as defined under Idaho Code §39-1102, and then only for those students who reside at least 1 ½ miles from the nearest appropriate school by road, unless it is the school boards’ judgment that the age, health, or safety of the pupil warrants transportation (handled through Safety Busing). Allowance is made for “Courtesy Busing” of students within 1 ½ miles of the school, provided that space is available and that the student’s pick-up and drop-off locations do not require the bus to change its existing route.

The student transportation funding formula can be divided into three parts. The base transportation reimbursement is the first of these and it serves as the base upon which the other portions are built. This portion works slightly differently for a contracted transportation program compared to a school-owned program as the costs of a contracted program cannot be broken down to the degree required of a LEA-owned fleet.

Under Idaho Code §33-1006(5) district or charter school owned program’s costs are divided between the reimbursable expenses for Idaho Department of Education transportation training, Idaho Department of Education transportation assessment fees, bus depreciation, and bus maintenance, all of which are reimbursable at 85%. All other reimbursable expenses are reimbursed at 50%

Because contracting programs do not break down their payments to their vendors to this level, a blended average is applied to these programs using the proportions of all district/charter school owned programs which average around 60%.

As part of the claim process, this base reimbursement must also be adjusted to remove the cost of any ineligible student riders (those properly enrolled in public schools who do not otherwise meet the requirements above), non-public school student riders, or any other non-student riders.

The second component of the student transportation funding formula is the funding cap model. Starting with fiscal year 2003-2004’s claims reimbursed in fiscal year 2004-2005, a funding cap was applied under Idaho Code §33-1006(5).

Under this statute, each transportation program’s reimbursable expenses (not including Idaho Department of Education assessment fees or payments to parents in-lieu of bus transportation) are divided by the districts’ total reimbursable mileage and total ridership (as determined by the highest single count day of the three weeks selected by the Idaho Department of Education each year) to obtain an average cost per rider and average cost per mile.

This is then compared to the statewide averages for these two figures and if the program exceeds 103% of both the statewide average cost per rider and the statewide average cost per mile, the funding for that program is capped at 103% of whichever average cost is more beneficial to the district or charter school.

A funding cap model is run in December of each year to give programs a starting estimate of their reimbursement, and then run again in February, May, and at the end of the fiscal year.  Foundation payments are distributed in February, May, and at fiscal year-end.

Programs may apply for a waiver of the 103% cap if specific routes meet two of the following three criteria, pending State Board of Education approval:

1. The number of student riders per mile is less than 50% of the statewide average;
2. Majority of miles are run on unpaved surfaces; or
3. Over 10% of the miles driven on the run are a 5% slope or greater

The block grant is the third and final component of the student transportation funding formula. Starting with fiscal year 2008-2009’s reimbursement in fiscal year 2009-2010, a block grant was added to the funding formula under Idaho Code §33-1006(7). It was at this time that reimbursements moved from a flat 85% reimbursement rate to the current 50%/85% split mentioned above.

The first year’s block grant was defined as the difference between what the program would have received under the flat 85% reimbursement model, and what they received under the split 50%/85% reimbursement model. The initial year block grant was then divided by the total number of support units the LEA had in that first year, and this amount is used as the basis for future block grant calculations.

Each year, this base block grant amount is multiplied by the district or charter school’s current year support units, then the resulting amount is modified by the percentage change in total statewide transportation reimbursements from the first year to the current year, minus the percentage change in total statewide enrollment from the first year to the current year.

Traditionally, reimbursements were reduced by a $7.5 Million Proportional Adjustment. The Legislature shifted 10% of the transportation funding to discretionary funds for the fiscal year 2009-2010 reimbursement paid in fiscal year 2010-2011. The following two years this budget adjustment continued as a $7.5 million proportional adjustment, reflecting approximately a 10% reduction per program.  In the fiscal year 2012-2013 payment, this adjustment was made permanent through Idaho Code §33-1006(8).

House Bill 396 of 2025 removed the $7.5 million Proportional Adjustment, effective for the FY 2026 reimbursement (for costs incurred in FY 2025).  Going forward, these funds will no longer be reduced from each school’s reimbursement.  

Senate Bill 1444 once again added the $7.5 million Proportional Adjustment, effective or FY 27 on a onetime basis.  For FY 27 the department has been once again directed to reduce the funding from each school’s reimbursement. 

Some charter schools may be eligible for the Advance Payment according to Idaho Code §33-5207(5). This means that they can receive reimbursement for current fiscal year transportation claim, although the fiscal year has not closed and the actual claim has not been audited yet.

The Idaho Department of Education is authorized to provide an advance payment of up to 60% of a public charter school’s estimated annual transportation costs.  The charter school shall provide an enrollment count of all students who are eligible for transportation as of the first Friday in November.   The final payment at the end of the fiscal year will reflect actual costs incurred in the prior fiscal year.

In addition, once actual expenditures from the prior year are finalized, they are recalculated using the full funding formula. Any difference between this recalculated amount and the advance payments previously received is trued up and distributed across the February, May, and end-of-year payments. 

According to Idaho Code §33-1501, no board of trustees shall be required to provide transportation for any pupil living less than 1.5 miles from the nearest appropriate school (exception, see Safety Busing). Also, according to Idaho Code §33-1502, no board of trustees shall be required to route school buses or other passenger equipment over any road not maintained as part of a highway district, county, state or federal highway system, or by the state or national forest service, except that the primary requirements to be observed by the board of trustees are the safety and adequate protection of the health of the pupils.

According to Idaho Code §33-1501, a board of trustees may require pupils who live less than 1.5 miles from the nearest established bus stop to walk or provide their own transportation.

Safety Busing is the transportation of pupils that live less than 1.5 miles as provided in Idaho Code §33-1501, when approved by the State Board of Education.

Whenever any student enrolls in and attends a school outside the district within which the parent or guardian resides, the parent or guardian shall be responsible for transporting the pupil to and from the school or to an appropriate bus stop within the receiving district.

According to Idaho Code §33-1502, whenever practical, routes shall be so established that no bus stop shall be more than 1.5 miles from the intersection of the driveway of the home of any pupil eligible for transportation and the nearest public road: except any road not maintained as part of a highway district, county, state or federal highway system, or by the state or national forest service.

There is currently nothing in Idaho Code that addresses the length of school bus rides.

According to Idaho Code §33-1502, the board of trustees of each school district may establish and alter bus routes and non-transportation zones. Such routes and zones shall be determined each year. A non-transportation zone is an area of a school district designated by the board of trustees which is impracticable, by reason of sparsity of pupils, remoteness, or condition of roads, to be served by established bus routes.

First, call your local school district office and ask to speak with the Transportation Supervisor. If you feel that your topics are not being addressed in a timely manner, call the principal of your school. If you still need to speak with someone after that, you can contact the district superintendent’s office or your school board trustee. The local school district should have contact information for the school board trustees on hand.
