INTRODUCTION
This advanced practice examination is designed around Florida septic tank
contracting, including contractor registration, permitting, onsite sewage treatment
and disposal system requirements, site evaluation, system sizing, tank and drainfield
construction, repairs, abandonment, septage management, and regulatory
compliance. The 2026/2027 emphasis reflects the current Florida regulatory
framework, including recent 2026 amendments to Chapter 62-6, F.A.C. Candidates
should be prepared to interpret requirements rather than merely recall terminology.
The questions emphasize professional judgment, regulatory application,
construction decisions, troubleshooting, documentation, and realistic field
scenarios. Florida septic tank contractors must understand both technical
installation requirements and the legal boundaries governing who may perform
regulated work.
Question 1
A contractor is preparing an application for Florida septic tank contractor
registration. The applicant has documented 2,500 hours of qualifying experience
and proposes to substitute several years of unrelated residential plumbing
experience for the remaining requirement. Which conclusion is most appropriate?
A. The unrelated plumbing experience automatically satisfies the remaining
requirement
,B. The applicant must document the required qualifying septic-related experience
recognized under the applicable rule
C. The applicant may substitute any construction experience if supervised by a
general contractor
D. The applicant may qualify solely by completing an approved continuing-
education course
🔴 Correct Answer: B. The applicant must document the required qualifying
septic-related experience recognized under the applicable rule.
🔵 Explanation: Florida registration eligibility depends on qualifying experience
recognized by the applicable statutory and administrative requirements. Experience
must fall within the categories authorized for septic tank contractor registration rather
than merely being general construction experience.
Question 2
A Florida septic contractor operates a corporation that offers septic tank
contracting services. The corporation has no certificate of authorization, although
one of its members individually holds an active septic tank contractor registration.
What is the most defensible compliance determination?
A. The individual registration automatically authorizes the corporation
B. The corporation may operate without authorization for its first year
C. The corporation generally must obtain the required certificate of authorization
D. The corporation is exempt because one member is registered
🔴 Correct Answer: C. The corporation generally must obtain the required
certificate of authorization.
🔵 Explanation: Florida distinguishes individual contractor registration from
authorization of a contracting business. Corporations, LLCs, partnerships, and
associations conducting septic contracting generally require the appropriate
certificate of authorization and qualifying contractor structure.
Question 3
A registered contractor's annual septic tank contractor registration expires on
September 30. The contractor submits a renewal application after the deadline but
,continues performing regulated septic work while waiting for approval. What is the
principal compliance concern?
A. The contractor remains active automatically for 90 days
B. The contractor's registration may revert to inactive status and regulated work
should not continue without proper active authorization
C. Only commercial projects are prohibited during the inactive period
D. The contractor may continue if the property owner signs a waiver
🔴 Correct Answer: B. The contractor's registration may revert to inactive status
and regulated work should not continue without proper active authorization.
🔵 Explanation: Florida requires annual renewal of septic tank contractor
registrations. Registrations not timely renewed revert to inactive status, and the
Department does not provide the normal contracting-related permitting and
inspection services for an inactive contractor.
Question 4
A state-licensed plumber is asked to install a septic system without obtaining a
septic tank contractor registration. The plumber argues that the plumbing license
eliminates all requirements applicable to septic work. Which response is correct?
A. The plumber is exempt from every septic regulation
B. The plumber is exempt only from the septic contractor registration requirement,
while other applicable septic requirements remain
C. The plumber needs no construction permit
D. The plumber may disregard septic system installation standards
🔴 Correct Answer: B. The plumber is exempt only from the septic contractor
registration requirement, while other applicable septic requirements remain.
🔵 Explanation: Florida recognizes an exemption from the septic tank contractor
registration requirement for qualifying state-licensed plumbers, but the exemption
does not eliminate permitting, inspection, installation, repair, maintenance, or other
applicable OSTDS requirements.
Question 5
During a proposed septic installation, the contractor discovers that the planned
drainfield location conflicts with a site limitation identified during evaluation. The
, owner insists that the contractor proceed because excavation equipment is already
mobilized. What should the contractor do first?
A. Proceed and document the conflict after installation
B. Modify the system without notifying the permitting authority
C. Reevaluate the proposed installation against applicable site and permitting
requirements before proceeding
D. Install the drainfield at the closest available location regardless of restrictions
🔴 Correct Answer: C. Reevaluate the proposed installation against applicable
site and permitting requirements before proceeding.
🔵 Explanation: Site limitations are fundamental to compliant OSTDS design and
construction. A contractor should not allow scheduling pressure or sunk costs to
override regulatory site-location requirements.
Question 6
A contractor is asked to construct a septic system substantially different from the
permitted configuration because the owner believes the revised arrangement will
improve performance. No revised approval has been obtained. Which action best
demonstrates professional compliance?
A. Construct the revision and request approval after completion
B. Obtain the necessary regulatory approval before implementing the material
change
C. Proceed if the revised design uses larger components
D. Proceed if the owner accepts financial responsibility
🔴 Correct Answer: B. Obtain the necessary regulatory approval before
implementing the material change.
🔵 Explanation: A contractor's professional responsibility includes constructing the
permitted system in accordance with applicable requirements. Material deviations
should not be treated as automatically acceptable merely because the proposed
modification appears technically beneficial.
Question 7
A contractor is evaluating a site where soil characteristics vary significantly across
the proposed drainfield area. Which approach is most technically defensible?
