Key Details

8 content domains: BIO, COG, SOC, DEV, ASS, TRX, ETH, RES. Delivered at Pearson VUE across 320+ centers. Supervised practice pass threshold is 450. The 50 pretest items are indistinguishable from scored items โ€” you cannot tell which count and which don't.

The 10-Step Question Pipeline

Every question on the EPPP passes through this gauntlet. Understanding it reveals how questions think.

Step 01

Job Task Analysis (JTA)

Surveys thousands of licensed psychologists to define what content gets tested. This is why the exam reflects real practice โ€” not textbook chapters.

Step 02

Item Development Committee (IDC1)

Recruits and trains volunteer item writers. Oversees the entire creation process and sets quality standards.

Step 03

Item Writers

Licensed psychologist volunteers write questions from home/office with references. Each item is peer-reviewed before advancing.

Step 04

IDC1 Domain Expert Review

Validates accuracy, relevance, mastery level, public protection value, and bias-free language. Items must demonstrate professional-level thinking.

Step 05

Style/Format Editing

Ensures compliance with EPPP style guidelines. Standardizes language, structure, and presentation across all items.

Step 06

Examination Committee (ExC1)

Reviews EVERY item. Must reach consensus. Checks clarity, language, correctness, and cultural sensitivity. These are the real gatekeepers.

Step 07

Pretesting

50 unscored items are mixed into live exams. Real candidates answer them under real conditions. Performance data is collected silently.

Step 08

Psychometric Analysis

Statistical evaluation of item performance. Differential Item Functioning (DIF) analysis identifies potential bias across demographic groups.

Step 09

Item Review Committee (IRC)

Reviews DIF-flagged items for cultural bias. Has authority to remove items โ€” but only 7 of 1,300+ have ever been pulled. The bar is surgical.

Step 10

ExC1 Final Review

Approved items become operational (scored). They enter the live item bank and count toward your pass/fail determination.

Scoring Mechanics

The EPPP uses Item Response Theory โ€” and understanding it changes your strategy.

Item Response Theory (IRT)

Unlike simple percentage scoring, IRT weights each question based on its difficulty, discrimination power, and guessing probability. Harder questions you get right boost your score more. The 225 raw responses are converted to a scaled score from 200โ€“800.

What This Means Strategically

~70% correct maps to a 500 scaled score (pass for independent practice). You can miss roughly 53 of the 175 scored items and still pass. But since 50 pretest items are mixed in and indistinguishable, you're effectively answering 225 questions without knowing which 175 count. Treat every question as scored.

The Noise Factor

50 pretest items represent 22% of your exam experience. They consume time, attention, and confidence โ€” even though they don't affect your score. This is by design. The pretests exist to calibrate future items, not to help you. Budget your energy accordingly.

What Our Audit Revealed

We ran 2,054 EPPP-style questions through a 4-model AI consensus analysis. The results challenge ASPPB's own domain classifications.

49.2%
Questions reclassified. Nearly half of all items were assigned to a different primary domain by our 4-model AI consensus than ASPPB's official classification.
87.3%
Cross-domain testing. The vast majority of questions test knowledge across multiple domain boundaries. Siloed studying by domain is a losing strategy.
32โ€“47%
Temporal Confusion is the #1 trap. Across ALL 8 domains, Temporal Confusion (confusing sequences, timing, developmental stages) is the most common trap type.
+45%
TRX over-assigned. Treatment questions were over-classified by 45% in official materials. Many "treatment" questions are actually assessment or ethics in disguise.
+124%
BIO under-assigned. Biological Bases questions were under-classified by 124%. Far more questions have a biological component than ASPPB's weightings suggest.

The Future: EPPP Reimagining

The current exam format has an expiration date. Here's the transition timeline.

Oct 2024

Part 2 Mandate Paused

The planned EPPP Part 2 (skills-based assessment) was put on hold after resistance from licensing boards and training programs.

Jan 2025

CITF Formed

A 14-member Content Integration Task Force was established to reimagine the EPPP from scratch.

Spring 2026

New Framework Released

New content domains, weighted categories, and sample questions will be published. This is when the new exam's shape becomes visible.

Q4 2027

New EPPP Launches

Integrated single-session EPPP replaces the current format. The 8-domain structure will be retired.

โฐ Window of Relevance

If you're taking the EPPP before Q4 2027, the current 8-domain format is your battlefield. Everything in this briefing applies. After that, new rules.

Strategic Implications

What this intelligence means for how you prepare.

Arizona Connection

AZ Representation on ASPPB Board

Arizona holds 2 of 7 ASPPB Board seats โ€” disproportionate influence for a single state. Mellott serves as President-Elect and Olvey as Secretary-Treasurer. This means Arizona's licensing perspective is heavily represented in exam governance decisions.
