What Are the SAP's Responsibilities?
The five core duties Part 40 assigns to a SAP across the full Return to Duty timeline. ← SAP Role & Process
Short Answer
Under Part 40, a SAP has five core responsibilities: conducting a clinical assessment and evaluation of the employee, referring the employee to an appropriate education or treatment program, conducting a follow up evaluation to determine successful compliance, providing the employer with a follow up testing plan, and providing continuing education or treatment recommendations. 49 CFR § 40.291(a)
Detailed Explanation
The Five Core Responsibilities
Section 40.291(a) lists the SAP's responsibilities in the Return to Duty process:
- Make a clinical assessment and evaluation of the employee, either face to face or, where the SAP's license permits, remotely using real time audio-visual technology meeting confidentiality and quality standards
- Refer the employee to an appropriate education or treatment program
- Conduct a follow up evaluation to determine whether the employee actively participated in, and successfully complied with, the recommended education or treatment (which may also be conducted remotely under the same criteria)
- Provide the DER with a follow up testing plan
- Provide recommendations for continuing education or treatment
A Sixth, Underlying Responsibility: Neutrality
Alongside these five functional duties, the SAP has an overarching obligation to remain neutral. The SAP is not an advocate for the employer or the employee; the SAP's function is to protect public safety through professional evaluation. 49 CFR § 40.291(b) This principle shapes how the SAP is expected to carry out each of the five functional responsibilities above.
How These Responsibilities Connect
These five duties are not independent tasks. They form a sequence: the initial assessment leads to a referral, the referral is later checked through a follow up evaluation, and depending on that outcome, the SAP sets a follow up testing plan and any continuing care recommendations. Each responsibility has its own detailed treatment elsewhere in this library.
Applicable Regulations
- 49 CFR § 40.291(a), listing the SAP's five core responsibilities
- 49 CFR § 40.291(b), establishing the SAP's neutral, public safety focused role
Professional Observation
In my experience, employees often understand the initial evaluation clearly but don't realize the SAP's responsibilities continue well past that first appointment. Knowing all five duties upfront can help set realistic expectations for how long, and how involved, the full process will be.
Common Misconceptions
Misconception
The SAP's job ends once the initial recommendation is made.
Reality
The SAP also conducts the follow up evaluation, sets the follow up testing plan, and provides continuing care recommendations. The role spans the full Return to Duty timeline, not just the first appointment. 49 CFR § 40.291(a)
Why the Confusion Occurs
The initial evaluation tends to be the most visible and emotionally significant appointment, so it's easy to assume it's the whole job.
Frequently Asked Questions
Does the same SAP have to handle both the initial and follow up evaluations?
Generally yes. The follow up evaluation is meant to build on the SAP's own initial assessment and referral, which is part of why authority to modify a recommendation based on new information is reserved for the original SAP. 49 CFR § 40.297
Is the SAP responsible for administering the follow up tests?
No. The SAP sets the follow up testing plan, but the employer is responsible for actually administering those unannounced tests. 49 CFR § 40.309
