DataChem Software: CSP, ASP, CIH, STS Certification Overview

If you’re preparing for a professional certification in occupational health, safety, or environmental management — the CSP, ASP, CIH, STS, or any of a dozen others — you’ve probably landed on DataChem Software at some point during your research. Maybe a colleague recommended it. Maybe you saw it listed alongside BoardVitals or Safety Exam Prep. Maybe you’re trying to figure out whether a $250–$750 investment is worth it before sitting an exam that could take months to retake.

This guide answers that question directly, with verified facts, real user feedback, and an honest assessment of where DataChem excels and where it falls short.

What Is DataChem Software?

DataChem Software, Inc. is a technology-based company specializing in preparation for professional exams. The company was started in 1986, selling a product that later became CIHprep. Since 2001, DataChem has been owned and operated by Cliff and Karen Goede.

That’s a 40-year track record in a niche that most people outside occupational health and safety have never heard of — and it’s the single most important fact about the company. DataChem is not a startup riding the online learning trend. It predates the internet as a certification prep provider and has spent four decades refining its product for one specific audience: working professionals who need to pass high-stakes industry exams.

DataChem has expanded its product line to include over 25 different certification preparation programs spanning Environmental Health and Safety, Healthcare Facility Management, Occupational Medicine, Occupational Nursing, Radiation, Case Management, and Supply Chain Management.

The company is based in Westborough, Massachusetts, at 69 Milk Street. President Hugh Oxnard and Customer Service Manager Marie O’Leary are the publicly listed contacts via the BBB profile — named leadership at a company this size is a meaningful trust signal.

What Certifications Does DataChem Cover?

This is the most-searched question about DataChem and the one most competing articles answer incompletely. Here is the full documented list of certification prep programs:

Environmental Health & Safety (EHS):

• CSP — Certified Safety Professional (CSPprep V10.0, 2,230+ questions across 9 exam domains)
• ASP — Associate Safety Professional (1,745 questions covering 9 BCSP blueprint topics)
• CIH — Certified Industrial Hygienist (DataChem’s original product, launched 1986)
• STS — Safety Trained Supervisor
• STS-C — Safety Trained Supervisor Construction (STSCprep V4.0, 625 questions)
• CHST — Construction Health and Safety Technician
• OHST — Occupational Health and Safety Technician
• CHMM — Certified Hazardous Materials Manager
• CET — Certified Environmental Trainer
• CPE — Certified Professional Ergonomist
• CIT — CITprep V1.0 (536 questions, 8 BCSP topic areas)

Healthcare & Clinical:

• Case Management (CCMprep V7.2, updated October 2022)
• Occupational Medicine
• Occupational Nursing
• Radiation programs
• Healthcare Facility Management

Supply Chain & Operations:

• Supply Chain and Inventory Management certifications

Human Performance:

• Human Physiology programs

The breadth is genuine. For anyone working across the intersecting fields of occupational health, environmental compliance, and healthcare facilities management, DataChem covers more certifications under one roof than any comparable provider.

How DataChem’s Exam Prep Programs Actually Work

DataChem assists clients with interactive programs that offer detailed explanations and progress monitoring. The mechanics matter because understanding the format helps you decide whether it fits your learning style before purchasing.

Every DataChem program is built around the same core structure:

• Practice question banks: Large sets of questions mapped directly to the official exam blueprint published by the certifying body (BCSP for safety certifications, ABIH for industrial hygiene, etc.). The CSPprep program contains 2,230+ questions. The ASPprep has 1,745. Each question comes with a detailed explanation and a reference — so you understand why an answer is correct, not just what the correct answer is.
• Progress tracking: The platform monitors which topics you’ve completed, your performance by section, and your overall readiness level. This matters practically because most certification exams have 8–12 distinct topic domains. Knowing you’re strong on hazard identification but weak on emergency response lets you focus study time efficiently rather than reviewing everything equally.
• Topic-selective practice: One verified user noted being able to “select which sections you get your questions from, which is nice so you can just focus on your weak sections.” This is a genuinely useful feature that not all exam prep platforms offer.
• Delivery formats: Programs are available in online, downloadable, or CD format. The online version works on any internet-connected computer, tablet, or smartphone. The downloadable version suits people with unreliable internet or who prefer to study offline. The CD format remains available for organizations with strict software procurement policies.

DataChem Software Pricing — What You’ll Actually Pay

DataChem programs are priced between approximately $250 and $750, depending on the certification and format. Individual users pay full price. Corporate purchases qualify for multi-user license discounts.

DataChem offers corporate discounts for multi-user licenses and a money-back guarantee, emphasizing their commitment to customer satisfaction.

The money-back guarantee is worth highlighting because it’s unconditional on exam outcome: if you don’t pass your exam, DataChem refunds your purchase price. This is a meaningful financial protection for candidates taking $400–$600 exams with strict retake windows.

If you’re deciding between DataChem and a competitor, spending 20 minutes on the free quiz gives you a direct sample of the question quality, explanation depth, and interface — far more useful than reading reviews alone.

DataChem Software Reviews — What Real Users Say

Synthesizing verified user feedback from BBB, Indeed, and Yelp gives a more complete picture than any single source.

What Users Consistently Praise

• First-attempt pass rates. The most consistent positive signal across independent reviews is passing on the first attempt. One verified Indeed reviewer who used DataChem for the CHST exam wrote: “Because it has multiple choice questions and questions similar to what you can expect from the actual test, it prepared me to pass on my first attempt.” A second reviewer confirmed similar results for a different safety certification.
• Flexible study format. Multiple reviewers note the self-paced, self-scheduled nature of the programs as a genuine benefit. “Flexible class hours” appears across several reviews alongside acknowledgment that the programs work well for employed professionals studying around work schedules rather than full-time students.
• Good value relative to exam cost. At $250–$295 for programs preparing you for exams that cost $400–$600 to sit — and which may cost months of delay to retake — the pricing is considered reasonable by most reviewers.

What Users Criticize

• Content can feel dated in some programs. The most pointed negative review on BBB described the product as “costly for the product delivered” with “questions and study guides that are poorly written.” This appears to reflect specific programs rather than the full library — the CSP and ASP programs benefit from more regular updates than some of the less-popular certification tracks.
• Requires prior foundational knowledge. One reviewer explicitly noted: “If you are trying to bone up on the basics, I would recommend the Span Training prep course.” DataChem is exam prep, not introductory education. It assumes you already understand the field’s fundamentals and need to practice for the specific exam format, not learn the subject from scratch.
• Interface is functional, not modern. DataChem’s platform does what it needs to do but doesn’t have the visual polish of newer learning platforms. For users who’ve spent time on modern edtech products, the interface will feel dated. For users who care primarily about question quality and pass rates, this is a non-issue.

BBB Accreditation Status

DataChem Software, Inc. is listed with the BBB serving Central and Western Massachusetts. The BBB profile confirms the company’s existence, address (69 Milk St, Westborough, MA), and leadership. Whether the company holds active BBB Accreditation at any given time is something to verify directly at bbb.org — BBB accreditation status changes based on whether a business maintains annual membership fees, and the BBB itself notes that businesses are under no obligation to seek accreditation.

DataChem CSP, ASP, CIH, STS — Program-Specific Details

DataChem CSP (Certified Safety Professional)

The CSPprep V10.0 is DataChem’s flagship product and the most purchased program. It prepares you for the Certified Safety Professional (V10) exam offered by the BCSP, with 2,230+ questions, answers, and explanations covering the 9 main domains on the exam. The CSP is one of the most valuable certifications in occupational health and safety; holder salary data consistently shows a significant premium over non-certified counterparts.

DataChem ASP (Associate Safety Professional)

The ASP program prepares you for the Associate Safety Professional exam offered by the BCSP, with 1,745 questions covering 9 topics outlined in the BCSP blueprint. The ASP is typically the stepping stone to the CSP for professionals building their safety credentials. Many employers require or prefer the ASP for mid-level safety roles.

DataChem CIH (Certified Industrial Hygienist)

The CIH program was DataChem’s founding product — the company literally started in 1986 with what became CIHprep. This is the most established program in the library with the deepest question bank and the longest development history. Industrial hygienists preparing for the ABIH exam have used DataChem longer than any other digital prep resource in this space.

DataChem STS (Safety Trained Supervisor)

The STS program is available alongside STS-C for Construction. The STS certification is aimed at supervisors and managers who need documented safety training credentials rather than full professional certification. It’s a lower barrier to entry than the CSP or CIH and correspondingly more accessible for frontline supervisors.

Who Should Use DataChem Software — And Who Shouldn’t

Use DataChem If:

• You’re an employed professional with foundational knowledge. DataChem’s self-paced format works best for people who already understand occupational safety, industrial hygiene, or healthcare management and need structured exam practice on top of that foundation.
• You’re preparing for BCSP or ABIH exams specifically. The question banks are mapped directly to official exam blueprints. This alignment is the product’s core technical value.
• Your organization is purchasing for multiple employees. The corporate multi-user discount makes DataChem cost-competitive for safety teams preparing several staff members for certification simultaneously.
• You want a refund guarantee. The pass-or-refund policy removes financial risk from the purchase in a way that few competitors match.

Look Elsewhere If:

• You’re building foundational knowledge from scratch. DataChem is exam prep, not introductory coursework. If you need to learn the subject matter before practicing for the exam, start with a foundational course through ASSP, AIHA, or a community college program, then use DataChem as the final exam preparation layer.
• You need the most current content for a recently revised exam. Some DataChem programs update their question banks promptly when certifying bodies revise their blueprints; others lag. Check the version number and release date of the specific program you’re purchasing against the current exam blueprint version from the certifying body.
• You prefer video-based learning. DataChem is text and multiple-choice throughout. If you learn best through video instruction, platforms like 360training or specific BCSP-affiliated prep courses offer video content that DataChem doesn’t.

How DataChem Compares to Competitors

DataChem’s differentiator is breadth combined with a 40-year content development track record and the pass-or-refund guarantee. For a professional who needs multiple certifications across safety and healthcare — a common career path in occupational health — DataChem’s unified library is more practical than maintaining subscriptions with multiple specialized platforms.

Promotional codes change periodically — if this code no longer works, check DataChem’s product pages directly as new codes are typically displayed as sitewide banners.

Q: What is the difference between DataChem CSP, ASP, and CIH programs?

These are three separate certification tracks. The CSP (Certified Safety Professional) is a senior-level credential from the BCSP requiring documented experience and passing a comprehensive exam — DataChem’s CSPprep V10.0 has 2,230+ questions. The ASP (Associate Safety Professional) is an earlier-career credential and a common stepping stone to the CSP. DataChem’s ASPprep has 1,745 questions. The CIH (Certified Industrial Hygienist) is the premier credential in industrial hygiene from the ABIH and was DataChem’s original product from 1986. All three programs use the same self-paced, question-bank format but cover different certification blueprints.

Q: Are DataChem Software programs worth the money?

For professionals who already have foundational knowledge in their field and are specifically preparing for a BCSP, ABIH, or other industry exam, the evidence from real user reviews supports the investment. Multiple verified reviewers confirm first-attempt pass rates, and the pass-or-refund guarantee removes the financial risk if you don’t pass. The programs are less appropriate for beginners who need introductory subject matter education rather than exam-specific practice. At $250–$295 for a program preparing you for an exam costing $400–$600 with potentially months-long retake windows, the value calculation is favorable for serious candidates.

Q: Does DataChem offer free practice materials?

Yes. DataChem provides free online practice quizzes at datachemsoftware.com/free-quizzes, accessible without purchase or account creation. These cover the main certification areas and give you a direct sample of question quality and explanation depth before committing to a paid program.
