Degree & Coursework Requirements
VerifiedBachelor's Required
Required
Degree Field
Bachelor's degree in soil science, agronomy, earth science, or a closely related natural science field with significant coursework in soil science
Graduate Degree
A graduate degree (MS or PhD) in soil science or a related field may reduce the experience requirement; each degree beyond the bachelor's may count as 1 year of experience
Required Coursework
Required coursework typically includes pedology, soil morphology, soil chemistry, soil physics, soil fertility, soil classification, and hydric soils; most licensing states require 15+ semester hours in soil science
Soil scientists typically need a bachelor's degree in soil science, agronomy, earth science, or a related natural science. Programs should include significant coursework in pedology, soil morphology, soil chemistry, soil physics, and soil classification. A graduate degree may reduce experience requirements in some states.
Professional Certification Requirements
VerifiedARCPACS Required
Not Required
SSSA Certification
Accepted
Exam
CSSE Fundamentals of Soil Science (FSS) and/or Principles of Soil Science (PSS) examinations
Maintenance
Maintain active license through 15 hours of continuing education per 1 year renewal cycle
The American Registry of Certified Professionals in Agronomy, Crops, and Soils (ARCPACS), now administered by the Soil Science Society of America (SSSA), provides the primary national certification for soil scientists. SSSA offers the Certified Professional Soil Scientist (CPSS) credential. Many licensing states accept or require ARCPACS/SSSA certification as part of the licensure process.
Professional Experience
Verified5 Years
Years Required
Professional experience in soil mapping, classification, interpretation, investigation, or evaluation under the supervision of a qualified/licensed soil scientist
Qualifying Experience
Texas requires 5 years of qualifying professional soil science experience under the supervision of a licensed or qualified soil scientist
Supervised Experience
Professional experience requirements for soil scientists typically range from 3 to 5 years depending on the state. Qualifying experience includes soil mapping, classification, interpretation, investigation, and evaluation. A graduate degree may reduce the required years of experience by 1-2 years in some jurisdictions. At least a portion of the experience must be under supervision of a qualified soil scientist.
State Licensure Requirements
VerifiedRequired
State Licensure
Professional Geoscientist - Soil Science (PG-SS)
License Title
Approximately 15 states require licensure or certification for soil scientists. In states without licensure requirements, soil scientists may still practice but often obtain ARCPACS/SSSA certification for professional credibility. The specific credential title varies by state (CSS, PSS, PSC, SE, or PG-SS).
Practice Areas & Authority
VerifiedSoil Mapping

Wetland Delineation
In Scope
Septic Design
Soil evaluation for on-site wastewater (septic) system design and permitting; site suitability assessment based on soil permeability, depth to water table, and restrictive layers
Environmental Assessment
Environmental site assessment including soil contamination evaluation, soil remediation planning, and environmental impact analysis
Land Use Planning
Soil-based land use planning including agricultural suitability assessment, development feasibility, stormwater management, and conservation planning
Erosion Control
Erosion and sediment control planning including construction site soil management, vegetative stabilization, and post-construction best management practices
Soil scientists provide expertise in soil mapping and classification, wetland delineation, septic system site evaluation, environmental site assessment, land use planning, and erosion control. The specific scope of practice varies by state and may overlap with other licensed professions such as geologists, engineers, and environmental scientists.

CE Details
15 continuing education hours per 1 year renewal cycle; must include courses in soil science, environmental science, or related professional development topics
Regulatory Board
Soil scientist licenses must be renewed on schedule with the governing authority. Continuing education requirements vary by state, typically ranging from 10-24 hours per renewal period. Some states require specific topics such as soil science advances, environmental regulations, or wetland science. Maintaining SSSA certification may also require ongoing professional development.
Out-of-State Reciprocity
VerifiedEndorsement Available
Yes
Reciprocity Requirements
States with soil scientist licensure may offer reciprocity or endorsement for practitioners holding licenses in other states. ARCPACS/SSSA certification is nationally recognized and portable across all states, providing a baseline of professional credibility regardless of state licensure requirements.
Texas licenses soil scientists through the Board of Professional Geoscientists as one of three geoscience disciplines (Geology, Geophysics, Soil Science). Requires passing both portions of the CSSE exam, a $255 initial license application fee plus $25 exam administration fee and $175 exam fee. The Professional Soil Scientists Association of Texas (PSSAT) advocates for the profession.
