Calculating percent of time in general education
By the IEP Atlas editorial teamLast updated
Short answer
To find the percentage of time in general education, divide the minutes the student spends inside the regular class by the total minutes in the school day, then multiply by 100. Count lunch, recess and specials as part of the day. A student out of class 65 of 390 minutes is inside the regular class about 83% of the day.
The percent of time in general education is a single number on the IEP that summarizes the least restrictive environment decision. It feeds your state's federal data report, and families often read it first. It is also easy to get wrong, because teams count the day differently.
This guide shows what to count, the formula, the federal reporting bands, a worked example and the mistakes that throw the number off. The number comes after the placement decision, never before it. For the decision itself, see how IEP teams decide placement and the least restrictive environment pillar.
What you need before you start
- The student's bell schedule for a full week, in minutes, from first bell to dismissal
- The service grid from the IEP, with minutes and the location of each service
- Your state's instructions for the educational environment field, since states set some counting rules
- A note on any rotating schedule, such as an A/B day or a specials rotation
The formula
Percent inside the regular class = (minutes inside the regular class ÷ total minutes in the school day) × 100.
Most teams work it out the other way. Add up the minutes outside the regular class, subtract from the total day, then divide. Both give the same answer.
Federal data on educational environments groups school-age students into bands by this percent: inside the regular class 80% or more of the day, 40% to 79% of the day, and less than 40% of the day, plus separate categories for separate schools, residential facilities, and home or hospital settings.[1] Your state form may ask for the exact percent, the band, or both.
The steps and the time each one takes
| Step | What you do | Time |
|---|---|---|
| 1. Set the total school day | Count bell-to-bell minutes, including lunch and recess | 5 minutes |
| 2. List every service with its location | Mark each as inside or outside the regular class | 10 minutes |
| 3. Average rotating schedules | Convert weekly minutes to a daily average | 5 minutes |
| 4. Add minutes outside the regular class | Sum all pull-out and separate-class minutes | 5 minutes |
| 5. Calculate and round | Apply the formula; round to a whole percent | 2 minutes |
| 6. Check the band and the statement | Match the band, then check the LRE wording agrees | 5 minutes |
Step by step
1. Set the total school day
Use the student's actual day from first bell to dismissal. Many state systems follow the federal approach of counting lunch, recess and study periods as part of the school day. If your student's day is 8:00 to 2:30, that is 390 minutes. A student on a shortened day has a shorter total; see shortened school days for when that is allowed.
2. List every service with its location
Go line by line through the service grid. Specially designed instruction, related services and supplementary aids each have a location. Services delivered inside the regular class, such as co-teaching or push-in speech, generally count as time inside the regular class. Services in a resource room, therapy room or special class count as outside. Check your state's manual if a service sits in a gray zone, such as a small group at the back of the regular classroom.
3. Average rotating schedules
Convert everything to the same unit. If speech is 2 sessions of 30 minutes a week outside class, that is 60 minutes a week, or 12 minutes a day on a 5-day week. Do the same for the total day if the schedule rotates.
4. Add minutes outside the regular class
Sum the daily minutes outside. Include separate lunch or separate specials if the student takes them in a special class. Leave out time the student spends with peers without disabilities in a general setting, such as the cafeteria with their class.
5. Calculate and round
Subtract the outside minutes from the total day, divide by the total, multiply by 100 and round to a whole number. Do not round to a nicer number to land in a band.
6. Check the band and the statement
Match the percent to the reporting band. Then read the LRE justification. If the statement says "most of the day in general education" and the number is 55%, one of them is wrong. The LRE justification examples show statements that agree with their numbers.
Worked example from start to finish
This example is fictional. Bella is in 6th grade. Her day runs 7:50 to 2:35.
Step 1. 7:50 to 2:35 is 405 minutes. That includes a 30-minute lunch and a 5-minute homeroom, so the total day is 405 minutes.
Step 2. Her IEP lists:
| Service | Minutes | Location | Inside or outside |
|---|---|---|---|
| Co-taught ELA | 55 a day | General education | Inside |
| Math intervention | 50 a day | Resource room | Outside |
| Speech-language therapy | 2 × 30 a week | Therapy room | Outside |
| Social skills group | 30 once a week | Counselor's office | Outside |
| Para support in science | 50 a day | General education | Inside |
Step 3. Weekly services become daily averages. Speech: 60 ÷ 5 = 12 minutes a day. Social skills: 30 ÷ 5 = 6 minutes a day.
Step 4. Outside minutes per day: 50 + 12 + 6 = 68.
Step 5. Inside minutes: 405 minus 68 = 337. Percent inside: 337 ÷ 405 × 100 = 83.2%, rounded to 83%.
Step 6. 83% falls in the "80% or more" band. The LRE statement says she is in the regular class for all subjects except math intervention, plus brief weekly speech and social skills sessions. The number and the statement agree.
If the team later adds a second 50-minute pull-out for writing, outside minutes rise to 118. Inside becomes 287 ÷ 405 × 100 = 70.9%, about 71%. That drops her into the 40% to 79% band. A change that size should prompt a real discussion, and if it amounts to a change in placement, prior written notice.[3] The change of placement guide explains when that applies.
Common mistakes
Weak: Leaving lunch and recess out of the total day. Better: Count the whole day bell to bell. Leaving them out shrinks the total and makes the percent look lower than it is.
Weak: Counting push-in services as time outside the regular class. Better: Count services delivered in the regular class as inside, unless your state says otherwise.
Weak: Mixing weekly and daily minutes in the same sum. Better: Convert every service to a daily average first.
Weak: Rounding 78.6% up to 80% so the student lands in the top band. Better: Report 79%. The band follows the number, not the other way around.
Weak: Calculating the percent first, then choosing services to fit. Better: Decide services and placement from the student's needs. The percent is a result, not a target.
Weak: Forgetting the separate lunch or separate specials. Better: If the student eats or takes art in a special class, those minutes count as outside.
Templates and tools
- The IEP services and minutes guide shows how to write the service grid this calculation depends on.
- The continuum of placements guide explains the settings behind the number for families.
- The service log helps you check that the minutes delivered match the minutes written.
- The glossary entry for service minutes defines the term for new team members.
The IEP must explain the extent, if any, to which the student will not participate with peers without disabilities.[2] The percent is a summary of that explanation, not a replacement for it.
Frequently asked questions
Does lunch count as time in general education?
If the student eats with peers without disabilities, it usually counts as part of the day and as time inside a general setting. Many state systems follow federal reporting instructions that count lunch, recess and study periods in the total day. Check your state's manual.
Do related services count as time outside general education?
Only when they happen outside the regular class. Speech therapy in a therapy room counts as outside. Speech therapy delivered during a class lesson counts as inside.
What is the 80% rule for inclusion?
There is no rule that a student must be in the regular class 80% of the day. Eighty percent is the top band in federal data reporting. Placement is decided on the student's needs, and the percent follows from that decision.
