So, the Regents. If you’re a New York high schooler or a parent of one, those words probably carry a certain weight. Specifically, the Earth and Space Sciences Regents. It’s the gatekeeper. For some, it’s a breezy walk through weather maps and rock types, but for others, it’s an absolute wall.
Why?
It’s not just the content. It’s the way the New York State Education Department (NYSED) structures the exam. It isn't just a "did you memorize this?" kind of test. It’s more of a "can you use this weirdly specific ESRT chart while being timed?" kind of test. Honestly, the Earth Science Reference Tables (ESRT) are basically the Bible of this exam. If you don't know them, you're sunk. Period.
What's Actually on the Earth and Space Sciences Regents Anyway?
We need to talk about the shift. For years, we called it Physical Setting/Earth Science. Now, things are moving toward the New York State P-12 Science Learning Standards, which are heavily based on the Next Generation Science Standards (NGSS). This means more focus on "doing" science rather than just "knowing" it. You’ve got to look at data. You’ve got to analyze patterns.
The exam usually splits into a few big buckets. Geology is huge. You’re looking at plate tectonics—the Mid-Atlantic Ridge, the San Andreas Fault—and how the crust moves. Then there's Meteorology. This is where people trip up on dew point and relative humidity. Astronomy is the "Space" part, dealing with the Big Bang, stellar evolution, and why the Sun seems to move across the sky even though we're the ones spinning.
The ESRT: Your Legal Cheat Sheet
You get a 16-page booklet. It’s called the Reference Tables. Use it.
Seriously, I’ve seen students try to memorize the specific heat of dry air. Why? It’s on page one. I’ve seen kids stress over the names of geologic eras. That’s a whole chart on pages 8 and 9. The biggest mistake is thinking you’re too smart to check the book. The test writers are tricky. They’ll ask a question where the answer is literally a direct look-up on the "Properties of Common Minerals" table, but they’ll phrase it so you think you need to calculate something.
You don't. Just look at the chart.
The Performance Test: The Part Everyone Forgets
Before you even sit down for the written exam in June, there’s the Lab Practical. Officially, it’s the Regents Examination in Physical Setting/Earth Science Performance Test. It’s usually about 15-20% of your total grade.
You’re at a station. You have a rock or a mineral. You have to identify it using a streak plate or by looking at its cleavage. Then you move to the next station and find the epicenter of an earthquake using a compass and some seismic data. Finally, you might have to determine the eccentricity of an ellipse. It’s hands-on.
If your teacher hasn't let you touch a stream table or a rock kit all year, start asking questions now. You can't "read" your way through identifying a piece of Galena. You have to see that metallic luster for yourself.
Why the Astronomy Section is Getting Weirder
Back in the day, you just had to know that the Earth orbits the Sun. Easy. Now, the Earth and Space Sciences Regents wants you to understand the red shift. They want you to explain why a star's spectral lines move toward the red end of the spectrum as it moves away from us. It's about evidence for the expanding universe.
Also, Kepler's Laws. You don't necessarily need to be a math genius, but you do need to understand that planets move faster when they are closer to the sun (perihelion) and slower when they are further away (aphelion). This usually shows up as a diagram of an orbit where you have to shade in areas of equal time.
Weather Patterns and the Infamous Station Models
Weather is the part of the exam that feels most like "real life," yet it's where the most points are lost. You’ll see a little circle with sticks and numbers sticking out of it. That’s a station model.
- The top right number is the barometric pressure.
- But wait, it’s in a code!
- If the number is "196," it actually means 1019.6 mb.
It’s these little technicalities that catch people. If you aren't practicing these specific conversions, you’re leaving points on the table. The Regents loves testing your ability to decode information, not just your ability to remember that "H" means high pressure.
Common Myths About the Regents Curve
There’s this idea that the curve will save everyone. While it’s true that the raw score to scaled score conversion is usually generous—meaning you don’t need a 65% raw score to get a 65 scaled grade—it isn't a magic wand.

In recent years, the "scaling" has become a bit tighter as the state moves toward these new standards. You can’t leave half the test blank and expect to pass. The Regents is designed to measure "minimum competency," but for students aiming for a Mastery score (an 85 or higher), the margin for error is tiny. One or two missed multiple-choice questions can knock you out of that top tier.
How to Actually Study (Without Losing Your Mind)
Stop reading the textbook cover to cover. It’s a waste of time.
Instead, go to the NYSED website and download the last five years of actual exams. Print them out. Do them. But here’s the trick: when you get an answer wrong, don’t just look at the right one. Go find where that answer was hidden in the Reference Tables.
If you can’t find it in the tables, then it’s a concept you need to memorize, like the Greenhouse Effect or the difference between a p-wave and an s-wave.
Focus on the Diagrams
The Earth and Space Sciences Regents is incredibly visual. Almost every other question has a map, a graph, or a cross-section of the Earth’s crust.
Spend time looking at "Topographic Maps." Learn how to draw a profile. If the contour lines are close together, it’s a steep hill. If they are far apart, it’s flat. If they V-shape over a river, the "V" points upstream. These are the "golden rules" that show up every single year.
Real-World Examples: The 2011 Japan Tsunami and the Regents
The test makers love using real-world events. You might see a question about the 2011 Tohoku earthquake. They’ll give you a map of the Pacific Ocean and ask you to calculate how long it took the tsunami to reach Hawaii.
This isn't just trivia. They want to see if you can use the $v = d/t$ (velocity equals distance over time) formula, even though it's a science test. Or they might ask you to look at the "Inferred Properties of Earth’s Interior" chart to tell them the pressure at the boundary between the outer core and the mantle.
Everything is interconnected. The earthquake happened because of subduction. The subduction happened because of density differences. The density differences happened because of the cooling of the Earth.
The Transition to Computer-Based Testing (CBT)
By 2026, the push for Computer-Based Testing is in full swing across New York. This changes the vibe. Instead of bubbling in a Scantron, you’re clicking.
For some kids, this is great. For others, it’s a nightmare because they can't easily draw on the diagrams. If you’re taking the test on a screen, make sure you’re using the "highlighter" and "eliminator" tools provided in the software. You still get scrap paper. Use it to draw your own diagrams if the digital ones feel too cluttered.
Is the "Space" Part Getting Harder?
Lately, yes. There’s a bigger emphasis on the lifecycle of stars. You need to know that our Sun is a main sequence star and that it will eventually become a Red Giant and then a White Dwarf.
Don't confuse "Luminosity" with "Temperature." On the H-R Diagram (Reference Tables, page 15), the temperature scale goes backward! The hottest stars are on the left, and the coolest are on the right. If you don't notice that, you’ll get every single astronomy question wrong. It’s a classic trap.
What to Do the Week Before the Exam
First, check your pens and pencils. You need a #2 pencil for the bubbles and a pen for the written parts.

Second, make sure you have a four-function or scientific calculator. You aren't allowed to use your phone, and you aren't allowed to use a graphing calculator unless your specific school district has a weirdly specific policy (usually, they don't allow them for Earth Science).
Third, do a "Table Run." Open your Reference Tables to page 1. Spend 5 minutes explaining every chart on that page to a wall, a dog, or a bored sibling. Move to page 2. Repeat until you hit page 16. If you get to a page and say, "I have no idea what these squiggly lines are," that’s your signal to go watch a YouTube tutorial on that specific topic.
Actionable Steps for Success
To move the needle on your score, stop guessing and start strategizing.
- Master the ESRT Index: Know exactly which page holds the "Average Chemical Composition of Earth’s Crust" versus "Rock-Forming Minerals." You shouldn't be flipping pages aimlessly during the test.
- Practice the "Rule of Vs": On topographic maps, the V-shape of contour lines always points toward the source of the water (uphill). This is a guaranteed 2-point question.
- Check the Units: The Regents loves to swap Celsius for Fahrenheit or kilometers for miles. Look at the axis of every graph before you even read the question.
- The "Check-Wait-Check" Method: For the lab practical, do your measurement, write it down, look away for thirty seconds, and then do it again. If the numbers don't match, you likely bumped your ruler or misread the triple-beam balance.
- Ignore the Distractors: Multiple-choice questions usually have two "garbage" answers, one "distractor" that looks right but is slightly off, and the correct answer. Cross out the garbage immediately.
- Time Management: You have three hours. That is plenty of time. If you’re rushing, you’re making mistakes. If you finish in 45 minutes, you definitely missed the nuances in the reading passages.
The Earth and Space Sciences Regents is a hurdle, but it’s a predictable one. The Earth doesn't change how it works between May and June. The rocks are the same, the stars follow the same paths, and the Reference Tables stay exactly as they are. Focus on the tools you're given, and the content will follow.
