Purdue Global and Walden University are two of the more cost-accessible online PMHNP options — but they’re built for different nurses. Purdue Global is a better fit if you’re cost-driven and want a fast MSN with a proven pass rate. Walden makes more sense if you’re eyeing a DNP, want someone else to handle preceptor placement, or need the lowest-friction path to getting enrolled.
The biggest practical difference: Purdue Global costs significantly less at both the MSN and certificate level, but comes with state enrollment restrictions that could disqualify you before you even compare curricula. Check that first.
Purdue Global is the better choice for cost and a built-in MSN-to-DNP pathway with a strong published pass rate. Walden is the better choice for nurses who want BSN-to-DNP access, a formal clinical placement pledge, and the most streamlined admissions process in this comparison.
Quick Take
- Choose Purdue Global if you want the lowest certificate cost, continuous start dates, a 93.7% published certification pass rate, and an MSN-to-DNP pathway where clinical hours carry forward.
- Choose Walden if you want a BSN-to-DNP option, a formal Practicum Pledge backed by a dedicated field placement team, and zero barriers to apply — no essay, no application fee, no GRE.
Important difference:
- Purdue Global has meaningful state enrollment restrictions that vary by track — multiple states including New York, Oregon, Washington, and Hawaii are excluded from one or more programs.
- Walden does not list the same restrictions. Confirm eligibility before applying to Purdue Global.

Cost Comparison
Purdue Global is less expensive at both the MSN and certificate level. Its MSN comes in at $32,760 versus Walden’s $44,705 — a $11,945 gap. On the certificate side, Purdue Global’s $20,160 is $15,065 less than Walden’s $35,225.
One important caveat: Walden’s figures reflect post-scholarship pricing after the Believe & Achieve Scholarship. Students who do not qualify or lose eligibility mid-program will pay more. Purdue Global’s estimates are standard-rate figures. Compare pre-scholarship numbers directly with Walden before making a cost-based decision.
Both schools use quarter credits, so per-credit rates are more directly comparable here than in other school pairings. Even so, Purdue Global’s $420/credit NP rate is significantly lower than Walden’s $775/credit NP specialization rate. For DNP coursework, Purdue bills at $700/credit versus Walden’s $925/credit — a meaningful difference for nurses going all the way to doctoral preparation.
Program Format and Flexibility
Both schools are fully online with no required campus visits and allow clinical placements to be completed locally or at the student’s own workplace.
The key format difference is start date flexibility — Purdue Global offers continuous enrollment, while Walden’s start date cadence is not specified in published materials. For working nurses who need to time enrollment around life events, Purdue Global’s continuous starts are a practical advantage.
PMHNP Program Options
Purdue Global offers three tracks: a postgraduate certificate, a BSN-to-MSN, and an MSN-to-DNP where clinical hours from the master’s portion carry forward into the doctorate. Walden offers four: a Post-Master’s Certificate, an MSN, a BSN-to-DNP, and an MSN-to-DNP. Walden is the only school of the two with a confirmed BSN-to-DNP PMHNP pathway.
- BSN-prepared nurses targeting an MSN — Purdue Global is faster (~2 years) and significantly cheaper ($32,760 vs. $44,705).
- BSN-prepared nurses targeting a DNP — Walden is the only option with a direct BSN-to-DNP PMHNP track.
- MSN-prepared nurses adding PMHNP specialty — Purdue Global’s certificate is $15,065 less than Walden’s.
- MSN-prepared nurses targeting doctoral practice — Both schools offer an MSN-to-DNP pathway; Purdue Global’s is lower cost at the MSN stage.
Admissions Requirements
Walden has the simpler admissions process — no application fee, no essay, and no GRE or standardized test scores required across all four tracks. Purdue Global requires a minimum 2.5 GPA for the certificate, a cleared background check, and evidence of national certification for APRN applicants. Neither school requires the GRE. For nurses who want to move quickly from decision to enrollment, Walden removes more friction.
⚠️ Purdue Global has meaningful state enrollment restrictions that vary by track. Excluded states include New York, Oregon, Washington, Hawaii, Louisiana, Utah, and others depending on program. Students must confirm eligibility before applying.
Clinical Placement and Student Support
Walden publishes specific clinical hour requirements: 640 hours for the MSN and certificate, and a minimum of 1,000 post-baccalaureate hours for DNP tracks (with at least 400 at the doctoral level).
Purdue Global does not publish a total clinical hour count — hours are distributed across six clinical credit courses.
On placement support, Walden’s Practicum Pledge explicitly commits the Field Placement Team to finding a preceptor site if a student cannot secure one independently — the strongest placement guarantee in this comparison. Purdue Global offers faculty- and preceptor-guided local placements with a workplace option, but stops short of a formal guarantee.
Purdue Global differentiates itself with immersive VR assignments covering telehealth and group therapy scenarios. Walden uses a virtual skills lab for practicum preparation. Both approaches offer simulation-based readiness tools beyond traditional coursework.
Outcomes
Purdue Global publishes a 93.7% NP certification pass rate for 2024 graduates across AANP, ANCC, and AACN exams. Walden does not publish a comparable figure. For students who weight outcomes data in their decision, Purdue Global provides a verifiable benchmark. Walden applicants should request this data directly from the school before enrolling.
Which PMHNP Program Should You Choose?
Choose Purdue Global if you want the lowest MSN and certificate costs at standard rates, continuous start dates, a published 93.7% certification pass rate, and an MSN-to-DNP pathway where clinical hours carry forward. Confirm your state is eligible before applying.
Choose Walden if you want a BSN-to-DNP PMHNP option, a formal clinical placement pledge with a dedicated field team, transparent clinical hour benchmarks, and a zero-friction admissions process. Verify whether you qualify for the Believe & Achieve Scholarship before using published cost estimates in your planning.
Both programs are CCNE-accredited and fully online with no required campus visits. The better choice depends on your degree goal, budget, whether your state qualifies for Purdue Global enrollment, and how important a placement guarantee is to you.
