What is SAFMEDS? The Complete Guide to Fluency-Based Learning

You've spent hours studying flashcards. You can recite definitions when you flip through them slowly. But when exam day arrives and time pressure mounts, you freeze. The terms you "knew" yesterday suddenly vanish from memory.

If this sounds familiar, you're not alone—and it's not your fault. The problem isn't how much you study; it's *how* you study. Traditional flashcard methods build recognition, not fluency. And in high-stakes situations like certification exams, fluency is what separates those who pass from those who don't.

This comprehensive guide introduces you to SAFMEDS (Say All Fast Minute Every Day Shuffled)—an evidence-based study method that transforms how you learn and retain information. Developed from decades of behavioral research, SAFMEDS doesn't just help you memorize terms; it builds the kind of automatic, fluent knowledge that stays with you under pressure.

By the end of this guide, you'll understand:

The Problem with Traditional Studying

Meet Sarah. She's a first-year graduate student in Applied Behavior Analysis, preparing for her BCBA certification exam. Like most students, Sarah creates flashcards for every term in the BACB Fifth Edition Task List. She reviews them every night, flipping through slowly and feeling confident when she can recall most definitions.

But during her first practice exam, something frustrating happens. Under timed conditions, terms she "knew" become inaccessible. She stares at questions, knowing she studied the answer, but unable to retrieve it fast enough. Her practice score: 62%. Passing requires 85%.

Sarah's experience reflects a fundamental misunderstanding about learning that affects most students.

The Numbers Tell the Story

Many candidates find the BCBA exam challenging despite months of preparation. The RBT exam, while less comprehensive, also presents difficulties for those who rely on traditional study methods.

Why? Because most study techniques optimize for the wrong outcome. Traditional flashcard review builds:

But certification exams require:

The gap between what traditional studying builds and what exams require explains why so many well-prepared students fail.

What the Research Says About Fluency

The concept of behavioral fluency emerged from decades of research in Precision Teaching, founded by Dr. Ogden Lindsley in the 1960s. Lindsley, a former student of B.F. Skinner, observed that accuracy alone was insufficient for true mastery. Students could be 100% accurate on a skill yet still perform poorly when conditions changed.

This led to a revolutionary insight: fluency requires both accuracy AND speed.

Defining Behavioral Fluency

Carl Binder, one of the leading researchers in fluency-based instruction, defines fluency as "that combination of accuracy plus speed of responding that enables competent individuals to function efficiently and effectively in their natural environments" (Binder, 1996).

In practical terms, fluent performance has four critical outcomes, known by the acronym RESA:

Traditional flashcard review might build accuracy, but only fluency-based practice builds all four RESA outcomes.

The Research Evidence

Research has examined fluency-based instruction compared to traditional methods. Key researchers in this area include:

The research suggests that when you practice responding quickly and accurately, you may build stronger retrieval pathways for stored knowledge.

Why Speed Matters for Memory

From a cognitive science perspective, speed-based practice strengthens neural pathways through repetition under optimal challenge conditions. When you practice recalling information quickly:

This explains why someone can "know" information but fail to access it under pressure—without speed training, the retrieval pathway isn't strong enough to function reliably when stress consumes cognitive resources.

The SAFMEDS Method Explained

SAFMEDS stands for Say All Fast Minute Every Day Shuffled. Each word represents a critical component of the methodology:

S - Say (Active Recall)

The first principle distinguishes SAFMEDS from passive review. You must actively produce the response—saying it aloud (traditional) or typing it (TAFMEDS).

Why it matters: Recognition ("I've seen this before") and recall ("I can produce the answer") use different cognitive processes. Recognition is easier but doesn't build the retrieval strength needed for exams. Active recall forces your brain to reconstruct the information, strengthening memory traces.

Traditional flashcards fail here when you flip a card, see the answer, and think "I knew that." You didn't—you recognized it. SAFMEDS forces genuine recall before checking.

A - All (Complete Coverage)

Practice with your complete card set, not just the ones you find difficult. Every term needs regular activation to maintain fluency.

Why it matters: Memory research shows that items you "know well" can decay without practice. The feeling of familiarity often persists longer than actual recall ability, creating dangerous blind spots.

Traditional flashcards fail here when you sort out "easy" cards and only study difficult ones. Those "easy" cards will surprise you on exam day.

F - Fast (Speed Building)

Respond as quickly as possible while maintaining accuracy. Speed is not just a byproduct of practice—it's a core training target.

Why it matters: Slow, deliberate responding indicates fragile knowledge. Fast responding indicates automatic, stable knowledge. The goal isn't just to know the answer but to access it instantly.

Traditional flashcards fail here when they allow unlimited time per card. Without time pressure, you never build the speed that distinguishes fluency from mere accuracy.

M - Minute (60-Second Timings)

Practice sessions are timed in 60-second intervals. This duration is optimal for maintaining intensity while allowing enough responses to measure improvement.

Why it matters: The one-minute timing creates urgency without exhaustion. It's short enough to maintain maximum effort but long enough to generate meaningful data (typically 20-50 responses).

Traditional flashcards fail here when study sessions have no time boundaries. Without timing, practice naturally slows, losing the urgency that builds speed.

E - Every (Daily Practice)

SAFMEDS is designed for daily practice. Brief, consistent sessions outperform longer, sporadic ones.

Why it matters: Memory consolidation requires spaced repetition. Daily practice spaces retrieval attempts optimally, strengthening memories with each session.

Traditional flashcards fail here when studying happens in long, cramming sessions before exams. The brain needs sleep between practice sessions to consolidate learning.

D - Day (Consistency)

Building on "Every," this emphasizes that practice should happen every calendar day, including weekends.

Why it matters: Consistency compounds. Missing days creates variability that makes progress harder to track and maintain. Habits form through unbroken chains of behavior.

Traditional flashcards fail here when studying happens only "when there's time." Fluency requires the reliability that comes from daily commitment.

S - Shuffled (Random Order)

Cards must be thoroughly shuffled between timings. Never practice in the same order twice.

Why it matters: The brain is incredibly good at learning sequences. If you always practice cards in the same order, you'll develop positional memory—remembering that "the third card is operant conditioning"—rather than learning the content. Shuffling prevents this.

Traditional flashcards fail here when you practice in consistent order or group cards by category. This creates artificial structure that won't exist on exams.

How SAFMEDS Differs from Regular Flashcards

The table below summarizes the key differences between traditional flashcard methods and SAFMEDS:

The Timing Makes the Difference

Consider two students studying the same 50 terms:

Student A (Traditional): Reviews all cards in 30 minutes, self-paced. Can recall all terms with enough time. Feels confident.

Student B (SAFMEDS): Completes six 60-second timings (6 minutes of active practice). Sees 35 cards per minute by the end of the week. Knows exactly which terms need work based on data.

After two weeks:

The difference becomes obvious on exam day. Student A "knows" the material but can't access it quickly enough. Student B responds automatically, finishing with time to spare.

The Science of Timed Practice

Why does 60 seconds work so well? Several factors converge to make this duration optimal:

Optimal Challenge Point

Sports psychology research identifies an "optimal challenge point" where task difficulty maximizes learning. Too easy, and you're not challenged enough to improve. Too hard, and you become frustrated and disengage.

The 60-second timing creates this optimal challenge by:

Automaticity Development

Cognitive psychologists distinguish between:

Fluency represents the transition from controlled to automatic processing. Timed practice accelerates this transition by forcing faster responses than controlled processing allows.

When you practice faster than you can consciously think, you're training automatic processing. This is why SAFMEDS produces such durable learning—you're building reflexes, not just memories.

The Testing Effect

Decades of research confirm the "testing effect": actively recalling information strengthens memory more than re-reading or passive review (Roediger & Karpicke, 2006). Each SAFMEDS timing is essentially a test, multiplying the memory benefits compared to traditional study.

A single 60-second timing might include 30+ retrieval attempts—30+ opportunities to strengthen memory through testing. Compare this to passively re-reading flashcards, where zero active retrieval occurs.

Getting Started: Your 5-Step SAFMEDS Protocol

Ready to implement SAFMEDS? Follow this protocol for optimal results:

Step 1: Select Your Card Set

Choose a focused set of 30-50 terms to practice. This is small enough to see progress quickly but large enough to prevent memorizing card order.

For exam prep: Use terms from your certification task list

For coursework: Create cards for key vocabulary and concepts

For professional development: Target terminology you encounter regularly

Step 2: Shuffle Thoroughly

Before each timing, shuffle your cards completely. Don't just cut the deck—perform a full riffle shuffle at least three times.

For digital practice with TAFMEDS, shuffling happens automatically, ensuring true randomization impossible with physical cards.

Step 3: Set Your 60-Second Timer

Use a timer with a clear signal. When it starts, begin responding to cards as fast as you can while maintaining accuracy.

For each card:

Step 4: Count Your Responses

After each timing, count:

Your count per minute is the sum of both, though you'll track corrects and incorrects separately for progress monitoring.

Step 5: Record and Chart Your Data

After each session, record your counts on a Standard Celeration Chart or use TAFMEDS's built-in tracking. Look for:

Tracking Progress: The Standard Celeration Chart

The Standard Celeration Chart (SCC) is the gold standard for visualizing fluency progress. Developed by Ogden Lindsley, it uses a semi-logarithmic scale that reveals learning patterns invisible on standard charts.

Why Count Per Minute Matters

Traditional assessments use percent correct, but this metric has a ceiling. Once you're at 100% accuracy, there's no room to show continued improvement.

Count per minute has no ceiling. Even at 100% accuracy, you can always get faster. This makes it more sensitive to real learning gains and provides continuous feedback throughout the learning process.

Setting Fluency Aims

For most terminology-based learning, research suggests these fluency aims:

These aims represent the point where RESA outcomes (retention, endurance, stability, application) reliably emerge.

TAFMEDS Card Design Principles

Creating effective TAFMEDS cards requires more than just writing terms and definitions. Research on fluency-based flashcards (Lovitz et al., 2021; Adams et al., 2018) has identified five critical design principles that maximize learning effectiveness.

Principle 1: Economy of Expression

Definitions should be 2-5 words—key phrases, not sentences.

Traditional flashcards often include full textbook definitions:

> ❌ "A consequence that follows a behavior and increases the future probability of that behavior occurring"

This 14-word definition is too long for rapid typing. Instead, distill to the essential key phrase:

The 3-word version captures the same core meaning but can be typed in seconds rather than tens of seconds.

Why this matters for fluency:

Principle 2: Consistency of Length

All definitions in a deck should have similar word counts.

A well-designed deck:

A poorly designed deck:

Why this matters: Inconsistent lengths create unfair comparisons. A 12-word answer takes much longer to type than a 3-word answer, but both count the same in frequency calculations.

Principle 3: Word Associations Over Sentences

Focus on the 2-3 words that distinguish each concept.

Ask yourself: "What are the essential keywords that make this concept different from all others?"

Principle 4: Flexible Scoring with Variations

Include abbreviations and alternate phrasings as acceptable answers.

Professional notation should be accepted:

When creating cards, include 2-4 acceptable variations:

Why this matters: Rigid scoring creates false negatives. A student who types "SR+" knows positive reinforcement just as well as one who types the full term.

Principle 5: Minimal Reading Load

Keep terms short (1-3 words) so learners can read and respond quickly.

✅ Good terms:

❌ Avoid:

Why this matters: Every second spent reading the term is a second not spent responding. Short terms maximize response opportunities per timing.

Common Mistakes and How to Avoid Them

Even understanding SAFMEDS, students often make mistakes that undermine results. Watch for these common errors:

1. Practicing Too Infrequently

The mistake: Doing SAFMEDS only when you "have time" or only before exams.

The fix: Commit to daily practice, even if brief. Three daily 60-second timings (3 minutes total) beats one weekly 20-minute session.

Why it matters: Memory consolidation requires distributed practice. Cramming builds fragile memories; daily practice builds durable ones.

2. Not Shuffling Cards

The mistake: Practicing in the same order repeatedly, or only partially shuffling.

The fix: Shuffle thoroughly (3+ riffle shuffles) or use digital practice for true randomization.

Why it matters: Position memory is sneaky. You might think you're learning content when you're actually learning sequence.

3. Focusing Only on Accuracy

The mistake: Slowing down to ensure every response is correct, never pushing speed.

The fix: Accept some errors as the price of building speed. Aim for 85%+ accuracy while pushing pace.

Why it matters: Perfect accuracy at slow speed doesn't build fluency. You need the combination of speed and accuracy that comes from practicing at your challenge point.

4. Skipping the Timing

The mistake: Practicing with cards but not using a timer, going at your own pace.

The fix: Always use a timer. The 60-second constraint is essential, not optional.

Why it matters: Without time pressure, there's no urgency to build speed. You'll develop slow, deliberate responding that doesn't transfer to timed exams.

5. Not Tracking Progress

The mistake: Practicing without recording data, relying on subjective feelings of improvement.

The fix: Record every timing. Chart your progress. Review data weekly.

Why it matters: Feeling confident and being fluent are different things. Only data reveals your true progress and shows when changes are needed.

Real Results: What to Expect

When implementing SAFMEDS correctly, most students see:

Week 1: Baseline Establishment

Initial performance varies widely based on prior exposure. Don't be discouraged by low counts—you're establishing your starting point.

Typical Week 1:

Weeks 2-4: Rapid Improvement

This is where SAFMEDS shines. With consistent daily practice, you should see steady increases in count per minute.

Typical Weeks 2-4:

Weeks 5+: Fluency Achievement

Continued practice leads to fluency aims being reached. You'll notice qualitative changes in how you access information.

Typical Signs of Fluency:

Hypothetical Example

A hypothetical timeline for a graduate student preparing for the BCBA exam might look like:

Individual results will vary based on factors including prior knowledge, practice consistency, and learning goals.

Conclusion

SAFMEDS isn't just another study technique—it's a scientifically-validated approach to building the kind of fluent knowledge that performs under pressure. By combining active recall, timed practice, daily repetition, and careful progress tracking, SAFMEDS builds what traditional flashcards can't: automatic, durable, applicable knowledge.
