How to Build Your First SAFMEDS Deck: A Step-by-Step Guide
You've learned about SAFMEDS. You understand the science. Now comes the practical question: how do you actually create a deck that works?
Building an effective SAFMEDS deck isn't just about writing terms on cards. The quality of your deck directly determines the quality of your learning. A well-constructed deck accelerates fluency; a poorly constructed one creates frustration and wasted effort.
This guide walks you through the complete process—from selecting content to formatting cards to organizing your deck for optimal practice. By the end, you'll have everything you need to create SAFMEDS decks that produce genuine fluency.
Why Deck Construction Matters
Before diving into the how-to, let's understand why this matters so much.
SAFMEDS works by building automatic retrieval—the ability to access information instantly without conscious effort. But automatic retrieval only develops when:
A deck with vague prompts, multiple possible answers, or compound questions undermines every practice session. You might go through the motions, but fluency won't develop.
Step 1: Select Your Content Strategically
Start with Priority Material
Not all content deserves SAFMEDS treatment. The method is most valuable for:
For exam preparation, focus on:
Avoid SAFMEDS-Inappropriate Content
Some content doesn't fit the SAFMEDS format:
| Appropriate for SAFMEDS | Not Appropriate for SAFMEDS |
|---|---|
| "Define reinforcement" | "Explain how to conduct a preference assessment" |
| "What are the 4 functions of behavior?" | "Compare and contrast ABLLS-R and VB-MAPP" |
| "Name the researcher who developed Precision Teaching" | "Describe the ethical considerations in behavior intervention" |
Determine Deck Size
Research on fluency building suggests optimal deck sizes:
Smaller decks allow you to reach fluency faster. Once fluent on one deck, you can either expand it or create a new deck for additional content.
Step 2: Write Effective Card Content
The Anatomy of a SAFMEDS Card
Each card has two components:
Both components require careful construction.
Writing Clear Stimuli
The stimulus should:
| Weak Stimulus | Strong Stimulus | Why It's Better |
|---|---|---|
| "Reinforcement" | "Define: Reinforcement" | Clarifies that a definition is expected |
| "What's the difference?" | "Positive vs. Negative Reinforcement: Key difference?" | Specifies exactly what's being asked |
| "Behavior" | "In ABA, what is the technical definition of 'behavior'?" | Indicates the expected level of precision |
Writing Precise Responses
The response should:
| Weak Response | Strong Response | Why It's Better |
|---|---|---|
| "Making behavior happen more" | "A consequence that increases the future probability of a behavior" | Technically precise and complete |
| "There are four: attention, escape, tangible, automatic" | "SEAT: Social (attention), Escape, Access to tangibles, Automatic" | Uses a mnemonic and categorization |
| "It's the same thing as motivation" | "A temporary alteration in the value of a consequence and the frequency of behavior related to that consequence" | Matches technical definitions |
The One-Card-One-Fact Rule
Each card should test exactly one piece of knowledge. When you find yourself writing "and" in a response, consider splitting the card.

After (Split into Two Cards):
Pro Tip
Step 3: Format for Fluency
Keep Responses Speakable
SAFMEDS originally stood for "Say All Fast..." The response should be something you can vocalize quickly. This matters even for silent practice because:
Use Consistent Formatting Conventions
Establish patterns for different card types:
Definition Cards:
Identification Cards:
Relationship Cards:
Category Cards:
Include Mnemonics Strategically
For lists or categories, mnemonics accelerate fluency:
| Content | Without Mnemonic | With Mnemonic |
|---|---|---|
| 4 functions of behavior | "Attention, escape, tangible, automatic" | "SEAT: Social attention, Escape, Access, Automatic" |
| 7 dimensions of ABA | List all seven every time | "BATCAGE: Behavior, Analytic, Technological, Conceptually systematic, Applied, Generality, Effective" |
Step 4: Organize Your Deck Structure
Group by Topic or Source
Organize cards by the chapter, unit, or topic they come from. This allows you to:
Create Logical Progressions
Within each section, order cards from fundamental to advanced:
This progression means earlier cards provide scaffolding for later ones.
Use Tags or Categories
If your deck system supports tagging (like TAFMEDS), categorize cards by:
This enables targeted practice as exam day approaches.
Step 5: Review and Refine
Test Your Cards Before Committing
Before your first official timing, do a slow walkthrough:
Identify and Fix Problem Cards
During practice, note cards that consistently cause issues:
| Problem | Likely Cause | Fix |
|---|---|---|
| Frequent hesitation | Ambiguous stimulus | Clarify the question |
| Inconsistent responses | Multiple valid answers | Standardize the expected response |
| Always getting wrong | Response too long or complex | Split the card or simplify |
| Confusing similar cards | Cards too alike | Add distinguishing context |
Iterate Based on Data
After a week of practice, review your performance data:
Revise problem cards based on these insights. A deck is never "finished"—it evolves as you learn what works for your brain.
Continuous Improvement
Common Deck Construction Mistakes
Mistake 1: Cards That Are Too Complex
Problem Card:
This card is testing at least four things. Split it into:
Mistake 2: Vague or Ambiguous Prompts
Problem Card:
What's the question? Define it? Give an example? Explain the types? The stimulus must clarify expectations.
Mistake 3: Inconsistent Response Formats
Problem Deck:
Inconsistent formats make it harder to achieve fluency. Standardize your response structure.
Mistake 4: Including Unnecessary Information
Problem Card:
Unless all three pieces are equally important, split into separate cards focused on what actually matters.

Conclusion
Building an effective SAFMEDS deck requires intentionality at every step:
The time you invest in deck construction pays dividends throughout your learning journey. A well-built deck is a precision tool for building fluency. A poorly built deck is a source of frustration that undermines every practice session.
Start with one chapter, one topic, one unit. Build 20-30 cards following these principles. Practice with proper timing and shuffling. Then expand from there.
Your first deck won't be perfect—but it will be far better than a deck built without these principles. And with each revision based on your practice data, it will get better still.
