Description
Subtract recorded breaks from scheduled lesson minutes.
Educational records need explicit score maxima, optional-criterion policy, timing allowances, choice positions and group capacities. Optional points and their maxima must use the same inclusion rule. Nominal seat counts and supplied extension fractions do not establish actual accessibility, attendance, appropriate support or assessment fairness.
Subtract recorded breaks from scheduled lesson minutes.
When to use this tool
Use Lesson Contact Break Time Net Minutes when you already have scheduledMinutes, breakMinutes and need to subtract recorded breaks from scheduled lesson minutes.
How to use the tool and how it works
- Enter scheduledMinutes, breakMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read contactMinutes. Use the output convention below.
Require scheduledMinutes>=0 and breakMinutes in [0,scheduled]; return scheduled-breaks.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| scheduledMinutes | Scheduled Minutes | Required. Finite number; minimum 0. |
| breakMinutes | Break Minutes | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| contactMinutes | Contact Minutes | Required. Finite number. |

}Limitations and assumptions
- No attendance, instructional content, actual contact time or applicable credit-hour rule is established.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the complete rubric, course and accommodation policy, schedule and actual classroom arrangement for operational decisions. Work with the full records when scoring, grouping or access matters beyond one supplied count, tag comparison or time allowance.
