A 90 day ABA therapy progress helps families track visible gains in communication, routines, and behavior. Use this timeline to understand early ABA milestones.
Key Points:
Short delays in talking, play, or daily routines can feel bigger when therapy has just started. Parents want to know what will show up first and when. A 90 day timeline gives families a way to see how ABA moves from relationship building to actual communication and then to home carryover.
The sections below will walk you through the 12 weeks, tie them to common insurance review points, and show which skills usually show first.

ABA moves faster when sessions are frequent and long enough. National guidance has long said young children should receive at least 25 hours per week of intensive, planned activity, because that level of contact creates more chances to reinforce new behavior.
Mentioning this at the start helps families see why 2 to 3 short visits a week will not show the same pace of growth. Most programs use a simple sequence:
An ABA therapy progress report at 90 days should reflect these steps and should connect every goal to the data the therapist has been taking in those sessions through ABA progress tracking methods.
The first two weeks are about getting the child to stay, enjoy, and ask. If the learner does not like the session, no amount of programming will work. That is why early ABA progress is often social and emotional.
What usually happens in weeks 0–2:
Early on, families can write in a 90 day progress tracker that the child:
This is also a good point to mention what to expect in ABA therapy so parents understand that play, short tasks, and reinforcement are all part of therapy, not a distraction from learning.
By the middle of the first month, the child often knows the therapist, knows the room, and knows the reward patterns. This frees the therapist to teach cooperation.
A 2023 meta-analysis of 11 studies with 632 participants found that comprehensive ABA models improved developmental outcomes when teaching was systematic and repeated, which is exactly what happens in this stage.
Skills families often see in weeks 3–6:
This is also where “ABA progress” can be shared with caregivers in very concrete terms. Instead of saying, “She is doing better,” therapists can say:
Families should keep in mind that many programs recommend 25 to 40 hours per week of therapy for young children, and research still describes this intensity as a way to gain faster change. When hours are lower, these week-by-week gains can stretch out.

The last third of the 90 day timeline is where carryover starts. The therapist has enough session data to show that the skill is real. The BCBA can now probe whether it shows up at home or with another caregiver.
Many payer clinical policies require that continuation requests include clear documentation of progress within about 90 days, which is why this stage is tied to reporting.
What weeks 7–12 often target:
At this point, the BCBA can prepare an ABA therapy progress report that includes:
Because many insurers ask for proof of progress every 90 days, having this staged plan makes reauthorization simpler for families.
A written 90 day ABA therapy progress plan helps parents see where they are. It also keeps the therapist, RBT, and BCBA looking at the same outcomes. Families can build a simple tracker with the week ranges as columns and the target areas as rows.
Here is a simple version:
A tracker like this aligns well with a “90 day progress tracker” and shows any gaps before insurance review. It also gives a place to record parent training hours aligned with ABA parent training goals, which insurers often like to see listed in the same period. If a child missed several sessions, it will be clear why a goal did not move.

Children should receive ABA therapy for several months to several years, depending on age, goals, and progress. Young children often require 25 or more hours per week in intensive programs. Therapy continues while data shows gains in communication, behavior, or daily tasks and families observe real-life improvement.
ABA is effective at 25 to 40 hours per week for broad skill growth, especially in younger children. Fewer hours may still work when goals are narrow or parents reinforce skills at home. BCBAs determine the exact hours based on medical need and adjust them during reauthorization.
Stopping ABA therapy is appropriate when goals are met, behaviors are manageable with parent strategies, or progress plateaus despite goal changes. Families and BCBAs should review progress reports to decide on next steps. If insurance sees no progress over 90 days, a lower-intensity model may be recommended.
Families who want this kind of clear 90 day ABA therapy progress often do best with a team that pairs quickly, runs enough hours, and shows data in every review. ABA therapy services in Tennessee, New Mexico, Indiana, Georgia, Arizona, North Carolina, Maine, and Utah can give parents a structured start.
Total Care ABA focuses on teaching skills that show up in real homes, not just in the clinic. Parents can expect pairing in the first weeks, goal-focused teaching in weeks 3–6, and generalization in weeks 7–12 so their child’s effort is turning into daily function.
