One Room, One Cohort, Blended Learning — Grades 3-5

Description of Model

One popular model of micro-school hearkens back to the traditional one-room schoolhouse. In this model, one teacher provides instruction for up to 15 mixed-age students. Often, in this model, a learning management system is used to develop a personalized learning plan for each student combining digital learning and in-class project-based curriculum. Students attend school two or three days a week, attending an in-school “study hall” or homeschool for the other two or three days of the week.

For the purposes of this financial model, we have created a micro-school of one-cohort of 15 mixed-aged elementary (3rd – 5th grades) students that meet in a one room shared space for three days of the week. The other two days are available to students in a “study hall” format in which the students work independently at home or the teacher is available on site to provide guidance and assistance. Our model is based on a 10-month school year, August — May. We also modeled an identical school with a 30 student cohort.

Budget for the Model

The following “big picture” budget categories are provided with sample costs for the given micro-school model.


Oklahoma’s minimum teacher salary schedule ranges from $31,600 for a new teacher with no experience to $46,000 for a teacher with 25 years of experience and a doctoral degree (Oklahoma State Department of Education, 2017). In our example one teacher (teacher owner) will be hired to provide instruction to all 15 mixed-aged students. Included in our salary estimate is a 30% cost for benefits. Benefits include health insurance, FICA, Medicare, and other required employment costs. Overall salary costs will be determined by the Federal requirements for organizations of your size and the requirements of your state. For the purposes of this example, we have budgeted $40,000 for one teacher salary plus $12,000 for benefits for a salary total of $52,000. For the 30 cohort, we added one aide at a salary plus benefits of $25,000.

Facilities Rental

Based on space requirements of the State and the Department of Human Services, this model estimates a need of 30 square feet/child. Therefore, our square footage needs are 15 students x 30 square feet for a total need of 450 square feet. The cost per square foot is determined by the average cost of rental a commercial space in the location we want to open the school. Commercial rent in the area is available for $10-$20 per square foot. For the purposes of this budget, we have estimated $17 per square foot of shared space with no build out necessary. For 450 square feet of space we estimate a yearly lease of $7,650 ($17/square foot x 450 square feet).


Although some lease agreements will include utilities in the overall cost, other rental properties require you to pay for your own utilities. In addition, you may have to pay a common use fee for shared spaces such as entryways, bathrooms, and kitchen areas. If you are sharing a space with a larger organization, such as in this example, you may be responsible for a percentage of the utilities based on the square footage you are occupying. For the purposes of this example, we are including the utilities and cost of shared space in our $17/square foot rental cost.


As our micro-school target population is a mixed-age group of students ranging from 3rd to 5th grade, we will plan for several learning centers which offer flexible seating and opportunities for students to work individually, in small groups, or meet in one large group. In the first year, our estimate for furniture is $200 per student for a total of $3,000. We would assume that in subsequent years, furniture costs would be minimal, needed only for replacement or repair of damaged items. In this budget we assume an average useful life of 4 years resulting in an average annual cost of $50.


As this model is based on a blended learning environment, curriculum will include costs for a learning management system, online curriculum, and materials and supplies for use in the physical classroom. The price range for online curriculum varies depending on the level of support provided by the vendor. Mico-schools can access online open educational resources to create their own online curriculum at no cost or supplement with computer applications for as little as $.99 per application per student. Online curriculum can also be accessed through an outside vendor. The cost for this curriculum can range from #250 per course per student for fully developed and supported online curriculum to $850 per course for a teacher-led experience (teacher is provided by the vendor). For the purposes of this example, we will provide four online courses (math, science, English, and social studies) through an online course provided for $250 per course per student. This totals $1,000 per year per student or $15,000 per year for a class of 15 students. Additional curriculum costs for project based learning and in-class activities will be estimated at $25 per student per year for a total of $375.


Blended learning generally requires that each student have a personal device, e.g. a Chromebook. This budget assumes each student receives a Chromebook with an average life of 2 years.

Miscellaneous Costs

Mico-schools will assume several nominal costs related to general operation of a school. These may include security, repairs, and improvements on the building, copy supplies, marketing and advertising, and substitute teacher costs. These costs will be determined by your particular micro-school design and context. For the purposes of this example, we are budgeting $200 per month for miscellaneous costs for a total of $2,400.


Common types of insurance recommended for schools include general liability, educator’s legal liability, property, and crime. An insurance specialist that specializes in insurance packages for school can answer questions about the insurance coverage you need. For the purpose of this example we are estimating $1,200 a year for insurance.

School Year Estimate

The following sample budget is an estimate of the cost of our micro-school model with an enrollment of 15 students based on a 10-month calendar, August — May and a three-day school week. These numbers are estimates provided as a guide for how to complete the budget for your micro-school design. The Budget Line Item column includes our “big picture” budget items. The Assumption column is based on our estimates, but can be changed to reflect your context. The total cost column calculates the assumed cost times the number of units (number of students, number of months, etc.).


Budget Line Item Assumption Total Cost 15 Students Total Cost 30 Students
Salaries and Benefits $52,000/Teacher$25,000/Assistant $52,000 $77,000
Rent $17/sq ft $7,650 $15,300
Utilities Included
Furniture $50/Student $750 $1,500
Curriculum $1,025/Student $15,375 $30,750
Technology $100/Student $1,500 $3,000
Miscellaneous $200/Month $2,400 $2,400
Insurance $1,200/Year $1,200 $1,200
Total $79,675 $130,000


In this example, the total cost for the micro-school for Year 1 for 15 students is $79,675 or approximately $5,331.00 per student. For 30 students, the total cost is $130,000 or approximately $4,333 per student.

In this example, tuition is the main source of revenue for the school year. Although other revenues may be pursued (e.g. grants, sponsorships, donations) it is assumed in this example that these revenue sources are nominal compared to total revenue for the micro-school.

The following table estimates tuition revenue for our example and net income. Net income for the school year increases as tuition rates increase. Determining tuition costs is based on the number of students, comparison to similar schools in the area, analysis of the market, and recognition of the capacity of the target population.


Tuition Revenue for 15 Students Cost per Student Total Net Income
$79,965 ($5,331/Student) $5,331 $0
$90,000 ($6,000/Student) $5,331 $10,035
$95,250 ($6,350/Student) $5,331 $15,285
$97,500 ($6,500/Student) $5,331 $17,535


Tuition Revenue for 30 Students Cost per Student Total Net Income
$132,660 ($4,333/Student) $4,333 $0
$150,000 ($5,000/Student) $4,333 $20,010
$180,000 ($6,000/Student) $4,333 $50,010
$195,000 ($6,500/Student) $4,333 $65,010
