Ms. Chiamaka Okonkwo Clinical Director Seekonk River Behavioral Health Providence, United States

Application for ABA Therapist, Seekonk River Behavioral Health

Dear Ms. Okonkwo,

I am applying for the ABA Therapist post at Seekonk River Behavioral Health. I hold an active registered behavior technician credential through the Behavior Analyst Certification Board, I currently carry nine learners at about 30 direct service hours a week across a center-based program and a school contract, and I am available for morning and after-school hours including in-building school placements.

At Waybrook Behavioral Learning Center I run trial-by-trial, frequency, duration and partial interval recording in CentralReach, with data entered before end of shift on 99 percent of sessions over the last two years. The part I would most want to bring to your program is what that record makes possible: I flagged a three-week flat trend on an intraverbal program, the supervising analyst moved the reinforcement schedule to variable ratio and shifted mand training into the natural environment, and responding recovered within four sessions. I sit for interobserver agreement twice a month and serve as second observer for four other technicians.

I noticed that your program runs both center-based services and a school contract, and that you train technicians in-house rather than only at hire. That is the structure I have worked best in, and I would be glad to support onboarding for new technicians on measurement systems and same-day entry, which I have done for eleven people across three sites.

My credential is active and my crisis prevention and first aid certifications are current. I can start on two weeks' notice and would be glad to complete a practical observation as part of the process. Thank you for your time.

Sincerely, Nadifa Warsame

Summary

An ABA therapist cover letter names the caseload you can carry, the direct service hours you are available for, and the session data record behind both. This guide gives you a full adaptable letter, the openings that work, and the confidentiality line that decides whether a clinical director trusts the rest of the page.

ABA Therapist cover letter examples by experience level

An ABA therapist cover letter is a one-page letter telling a clinical director what caseload you can carry, how many direct service hours you are available for, and what your session data looks like.

In practice, those three facts are what a director is solving for. Staffing an ABA caseload is a scheduling problem with a documentation problem attached: someone has to cover the hours, and every covered hour must produce a record clean enough to bill. That is why a director reads a letter answering both twice.

Guide to an ABA therapist cover letter

In short, this guide and the corresponding ABA therapist cover letter example will cover:

  • First, how to structure the letter, paragraph by paragraph
  • Then, why hours and caseload belong in the first paragraph
  • Also, what a data sentence looks like, and why it beats a passion paragraph
  • The confidentiality line that decides whether a reader trusts the page
  • Finally, what the published numbers mean for the letter

Expert Tip

Put hours and caseload in the first paragraph

A clinical director reading applications is holding a grid of unfilled hours: after-school, early morning, a school contract needing someone in a building by 8am. Write the answer: "I hold an active registered behavior technician credential through the Behavior Analyst Certification Board, I have carried nine learners at about 30 direct service hours a week, and I am available for afternoon and after-school hours including a school placement."

Three facts in one sentence, and more useful than a paragraph about your commitment to the field.

In short, the pattern in every row: replace a feeling with a checkable fact, and a category with a name.

The data sentence, and why it does the work

However, almost every letter says some version of "collected and analyzed data". In fact, it is the most wasted sentence in the occupation, true of every applicant and descriptive of none. Instead, replace it with a sentence in three parts.

PartWhat it looks like
What you recordedTrial-by-trial across discrete trial teaching, frequency for elopement, duration for engagement, partial interval for stereotypy
Where it wentRecorded in session on a tablet in CentralReach, entered before end of shift on 99 percent of sessions
What it changedA flat trend I flagged led the analyst to change the reinforcement schedule; responding recovered in four sessions

Keep the credit accurate. Of course, you did not write the behavior intervention plan. You produced a record good enough for someone else to decide on, then carried that decision through. As a result, a director reads that as someone who understands their own role.

Do

Name your credential, its board and its status in the first paragraph. Give your available direct service hours as a number and a time of day. Name the measurement systems you have run and the data platform. Describe one thing a graph changed, crediting the analyst with the plan change. Name one real thing about how the provider runs services.

Iconly/Bold/Close Square Don’t

Do not open with a paragraph about your passion for the population. Do not claim a behavior intervention plan an analyst wrote. Do not invent an agreement percentage. Do not tell a story about a learner. Do not send a letter with no provider name in it.

The confidentiality line that decides the rest

However, one mistake costs the interview outright: telling a moving story about a specific child. It feels like evidence of care. To a clinical director it is evidence that you will discuss learners outside the record, in writing, to a stranger, before anyone hires you. Therefore, write groups, counts and programs instead. "Nine learners aged 3 to 11, four behavior reduction programs, two written safety plans" carries everything a director needs and breaks nothing.

Statistical insight

The published numbers around this job, and what they mean for the letter

The Bureau of Labor Statistics publishes no Occupational Outlook Handbook profile for ABA therapists or registered behavior technicians, so there is no federal wage or growth figure for the title.

The nearest published occupations show what market you are writing into. Psychiatric technicians and aides held 198,400 jobs in 2025 with 18 percent projected growth through 2035 and about 21,900 openings a year, at a combined median of $45,100 in May 2025. Social and human service assistants held 463,400 jobs with 7 percent growth, at a median of $45,930. Substance abuse, behavioral disorder and mental health counselors, the master's level destination occupation, had a median of $59,350 (BLS Occupational Outlook Handbook, May 2025 with 2025 to 2035 projections).

Growth at that rate with wages in that range means providers hire and lose people continuously. Your letter is read by someone who expects to fill this post again, so the sentences that matter predict whether you will still be there in a year.

Length, format and sending it

One page, four paragraphs, 250 to 400 words. PDF unless the portal says otherwise, named for yourself and the post: nadifa-warsame-aba-therapist-cover-letter.pdf.

Address a person. Clinical directors are usually named on a provider's site, and "To Whom It May Concern" reads as a file sent to twelve providers. Keep every number identical to your resume: our ABA therapist resume example uses the same figures.

Key takeaways

  1. First, put your credential, its board, its status and your available hours in the first paragraph.
  2. Then give caseload as a number of learners, an age range and a setting.
  3. Also, name the measurement systems you run and the platform they live in.
  4. In addition, give your data entry lag; supervisors care about it most.
  5. Describe one thing a graph changed; credit the analyst with the change.
  6. Above all, write groups and counts, never a story about a child.
  7. Finally, name one real thing about the provider.

ABA therapist cover letter questions, answered

How long should an ABA therapist cover letter be?

One page, four paragraphs, 250 to 400 words. Providers here recruit continuously and read in batches, and a long letter is read less carefully.

Do I need a cover letter if the provider uses an application portal?

Attach one wherever there is a field for it. The portal collects the same structured fields from everyone; the letter is the only place you can state your available hours by time of day, your documentation habit and what your data changed.

What do I write with no ABA experience yet?

Lead with your credential status and availability in direct service hours, then the work showing you can follow a written procedure with a person who needs support: school paraprofessional work, direct support for adults with disabilities, respite, camp, or childcare with a documented routine. Then say plainly that you document the same day; new hires are lost to backlogs more often than to clinical difficulty.

Should I name the data platform in the letter?

Yes. CentralReach, Rethink Behavioral Health, a proprietary platform or paper with next-day entry. A provider on the same platform reads a shorter onboarding; one on a different platform reads evidence that you can work inside a structured record.

How do I write about results without claiming the clinician's work?

Describe what you produced and what someone else decided. "I flagged a three-week flat trend; the supervising analyst changed the reinforcement schedule and responding recovered within four sessions" is accurate, generous and impressive at once. Claiming the plan change signals you do not understand your own boundary.
