Intervention Task Dependencies: Plan Prep in Order

Some intervention tasks can only happen after others. You can’t run a session without materials, you can’t copy materials you haven’t chosen, and you can’t follow up on a meeting that hasn’t happened. These links are called dependencies. Noticing them, and scheduling in the right order, is what keeps one delay from knocking over the rest of your week.

What is a task dependency?

A dependency means Task B needs Task A to be finished first. For intervention work, the most common chains look like this:

• Choose → make → copy → session. Selecting a passage, making word cards, copying, then teaching.
• Book space → set up → session. Reserving a room or table before you rely on it.
• Session → record → follow-up. Logging delivery in the approved system, then sharing updates.
• Prepare agenda → meeting → action tasks. Getting ready for a team meeting, then acting on its decisions.

How to find dependencies in your week

For each session on your schedule, ask:

1. What must exist or be ready before this starts?
2. Who or what else does that depend on, such as a copier, a booked room or a colleague?
3. What happens straight after this session?

Write each answer as its own task. The question “what does this need?” is usually enough to reveal every hidden step.

Scheduling in the right order

• Work backwards. Start with the session time, then date each earlier step before it with some slack.
• Leave a buffer for risky steps. Copying and anything involving another person deserves at least a day of margin.
• Mark the root task High. If the first step slips, everything after it slips, so protect it.
• Mention the link in the name or note. “Prep – copy passages for Wed group A” makes the dependency visible.

When a dependent task moves

RTI Scheduler doesn’t link tasks together, so moving one task won’t move the others. That keeps things predictable, but it means you check the chain yourself. When a session moves:

1. Edit the session’s date or time.
2. Look at its preparation tasks. Do they still finish before the new time?
3. Look at its follow-up. Does it still come after?
4. If the session moved earlier, check whether prep now needs to happen sooner.

Example chain

Task	Depends on	Scheduled	Priority
Prep – choose passages for Wed group A	–	Mon 3:30 PM	High
Prep – copy passages for Wed group A	Choosing	Tue 7:45 AM	High
T2 – Reading fluency group A (Room 12)	Copies	Wed 9:30 AM	High
Follow-up – log delivery in school system	Session	Wed 12:30 PM	Medium

Keep chains short

Long chains are fragile. Where you can, prepare in batches (for example, copy everything for the week in one task), so several sessions depend on one well-protected step instead of many small ones.

Three real dependency chains, start to finish

Dependencies are easiest to see in a full example. Here are three chains interventionists run every week, written backwards from the moment that matters.

A math group that needs manipulatives

1. Thursday 10:15 – T2 – Fractions group (Room 8). The session itself.
2. Wednesday 3:30 – Prep – sort fraction strips into four bags. Needs the strips to be cut.
3. Tuesday 3:30 – Prep – print and cut fraction strips. Needs the copier and a paper cutter.
4. Monday planning time – Prep – choose this week’s fractions skill. Everything else depends on this.

Notice that the root task is on Monday, three days before the session. That slack is what lets you survive a broken copier on Tuesday.

A team meeting that needs your input

1. Wednesday 2:45 – MTSS team meeting.
2. Tuesday – Prep – write two questions about group B for the agenda (no names).
3. Thursday – Follow-up – act on meeting decisions. See turning meeting notes into action tasks.

A session that moves rooms

1. Friday 9:30 – T3 – Phonics session (Library table, not Room 12).
2. Thursday – Prep – confirm the library table with the office.
3. Friday 8:45 – Prep – move the phonics box to the library.

A quick template you can copy

Paste this into your notes and fill it in for any session that keeps going wrong:

Step	Task name	Needs	Latest safe date
1	Prep – choose …	Nothing	3 school days before
2	Prep – make or copy …	Step 1	2 school days before
3	Prep – set up …	Step 2	Morning of, or day before
4	Session …	Step 3	Planned time
5	Follow-up – log …	Step 4	Same day

Common questions

Should every prep task be High priority?

No. Only the steps a session can’t run without, and the first step in a chain. A “nice to have” extra activity is Medium or Low. See how to prioritize preparation tasks.

What if a session repeats every week?

Repeat the session itself weekly, then repeat the prep that’s the same each week too, such as “Prep – copy passages for group A” the day before. Prep that changes from week to week is better added during your Friday review.
