You’re staring at a video of a woman’s hands moving at what feels like light speed, and your brain just... stalls. It’s that familiar panic. If you’ve ever considered taking an american sign language test, you know that moment. It isn’t just about memorizing "bathroom" or "thank you." It’s about the eyebrows. It’s about the lean. It’s about whether you’re actually communicating or just flapping your hands in a way that looks like a bird caught in a draft.
Most people think an ASL exam is a simple vocab quiz. It isn't. Not even close.
Whether you’re a nursing student trying to boost your resume or someone who actually wants to work as a professional interpreter, the landscape of testing is honestly a bit of a mess right now. Things have changed. Since the pandemic shifted everything online, the way we measure fluency has morphed, and frankly, some of the old "gold standard" tests are facing serious scrutiny from the Deaf community for being culturally out of touch.
Why the ASLPI is the Boss (And Why It’s Terrifying)
If you’re serious about this, you’ve heard of the ASLPI. That stands for the American Sign Language Proficiency Interview. It’s run through Gallaudet University, which is basically the Harvard of the Deaf world.
The ASLPI isn't a "fill in the bubble" test. You sit across from an interviewer—usually via a high-definition video link these days—and you just talk. For 20 to 30 minutes. It feels like a first date where the other person is judging your soul, except they’re actually judging your use of "classifiers" and "non-manual markers."
What most people get wrong is thinking they can study for this with a book. You can't. The interviewers will pivot. They’ll ask about your childhood, then jump to a complex political issue, then ask you to describe the layout of your kitchen. They are looking for "functional fluency." Can you actually survive in a Deaf environment without a pen and paper?
The scoring goes from 0 to 5. Getting a 5 is like being a unicorn. Most hearing people who have studied for years still land in the 2 to 3.5 range. A Level 3 is generally considered the "professional" threshold for many jobs, but don't beat yourself up if you start at a 1. Honestly, a 1 means you can at least say hello and ask where the bus is. That’s a start.
The Performance Assessment Gap
Then there’s the NIC—the National Interpreter Certification. This is the big one managed by the Registry of Interpreters for the Deaf (RID).
Here’s the thing: passing an american sign language test to prove you know the language is one thing. Passing a test to prove you can interpret is a completely different beast. Interpreting requires your brain to work in two channels simultaneously. You’re listening to English while producing ASL, or watching ASL while speaking English. It’s mental gymnastics that leaves you physically exhausted.
The NIC has been through some drama lately. There were transitions in how the test was administered, leading to massive backlogs. People were waiting months, sometimes over a year, just to get their results. It’s frustrating. If you’re looking to get certified in 2026, you need to check the current CASLI (Center for the Assessment of Sign Language Interpretation) portal every single day.
What’s actually on the performance exam?
- Ethics: They give you a scenario. Maybe a doctor is being rude to a Deaf patient. Do you step out of your role to defend the patient? (The answer is usually no, but it's nuanced).
- Transliteration: This is more like "Signed Exact English." It’s for clients who prefer English word order.
- ASL-to-English: This is where most hearing students fail. We spend so much time learning to sign that we forget how to speak "Deaf-influenced" English naturally.
The Secret Sauce: Non-Manual Markers
You can have the most beautiful handshapes in the world, but if your face is "flat," you will fail any reputable american sign language test.
I’ve seen students who knew every sign in the dictionary get a low score because their eyebrows didn't move. In ASL, your eyebrows are your grammar. They are your punctuation. Raising your eyebrows makes a statement a "Yes/No" question. Furrowing them makes it a "WH-" question (Who, What, Where).
If you aren't using your face, you're essentially speaking in a monotone, robotic voice. Imagine someone telling you their dog died with a huge grin on their face. That’s how it feels to a Deaf person when your signs and your facial expressions don't match.
State Exams vs. National Exams
Don't ignore the BEI. The Board for Evaluation of Interpreters started in Texas but has spread to several other states like Illinois and Michigan.

Some people find the BEI more "approachable" than the NIC, but "approachable" doesn't mean "easy." It’s just structured differently. The BEI has different levels (Basic, Advanced, Master). This is actually great for your career because you can get a "Basic" certification and start working in lower-stakes environments—like a basic office meeting—while you study for the "Master" level which would allow you to work in a courtroom or a high-pressure medical setting.
How to Actually Prepare (Without Losing Your Mind)
Stop using apps. Okay, don't stop using them, but realize they won't help you pass a test.
An app can't tell you that your "directionality" is wrong. For instance, the sign for "HELP." If I move the sign toward you, I’m helping you. If I move it toward me, you’re helping me. An app just sees a handshape. A proctor on an american sign language test sees a grammatical error.
- Record yourself. It’s painful. You’ll hate how you look. Do it anyway. Watch yourself on mute. Do you look like you’re actually saying something, or do you look like you’re doing the Macarena?
- Find a Deaf mentor. This isn't optional. You cannot learn a culture-based language in a vacuum. Pay a Deaf tutor for their time. It’s the best investment you’ll make.
- Vary your input. Don't just watch your teacher. Watch "Deaf YouTube." Watch different accents. Yes, there are regional accents in ASL. A "pizza" in New York doesn't always look like a "pizza" in California.
The Cost of the Test
Let’s talk money, because it’s a hurdle. These tests aren't cheap. Between the written knowledge exam and the performance exam, you’re looking at anywhere from $400 to $800. And that doesn't include the "maintenance" fees or the CEUs (Continuing Education Units) you have to earn later to keep your certification active.
It's a "pay to play" industry. But the ROI (Return on Investment) is there. With the current shortage of qualified interpreters, especially in legal and mental health settings, a certified person can command $50 to $125 an hour depending on the region.

The Ethics Component
Every american sign language test has a heavy focus on the Code of Professional Conduct (CPC). This is where the "Expert" part comes in. You aren't just a "helper." You are a communication bridge.
The biggest mistake is the "Savior Complex." If you go into an ASL test thinking you're there to "help the poor Deaf people," the evaluators will sniff that out in seconds. They want to see someone who respects Deaf autonomy. If a Deaf person wants to make a bad decision, your job is to interpret that bad decision accurately, not to fix it for them.
Common Pitfalls to Avoid
- English-isms: Avoid signing "I am going to the store." In ASL, we usually go with "STORE I GO" or "I GO STORE."
- Over-signing: Beginners try to sign every single "is," "and," and "the." Stop it. Those words don't exist in ASL.
- Mouth Morphemes: You shouldn't be mouthing English words. You should be using specific mouth shapes (like "cha" for something big or "mm" for something routine).
Next Steps for Success
If you’re feeling overwhelmed, just take the first bite. Don't look at the Master Level certification yet.
First, go to the CASLI website and look at the "Knowledge Exam" requirements. It's the written portion you have to pass before you can even touch the performance test. It covers history, culture, and ethics.
Second, find a local "Deaf Night Out" or a signing coffee chat. You need to get your "hands up" in the real world. Testing environments are sterile and stressful; real-world conversations are where the actual fluency happens.
Finally, check your state's specific laws. Some states require a license, some just require "certification," and some are a free-for-all. Knowing the legal requirement in your backyard is the only way to make sure your american sign language test results are actually worth the paper they're printed on.

Sign up for a mock interview. Many community colleges with ITPs (Interpreter Training Programs) offer them. Having a stranger tell you your "incorporation of numbers" is sloppy is much better than hearing it from an official examiner after you've already paid $500.
