EA/Science Cheat Sheet 2026: One-Page Review of Must-Know Facts

What This Cheat Sheet Covers (and What It Doesn't)

This page is a one-sitting review of the facts candidates most often confuse about National Board Certification in Early Adolescence/Science (EA/Science). The certificate is issued by the National Board for Professional Teaching Standards (NBPTS) and is designed for teachers of science to students ages 11-15. It is a teaching-practice credential, not a single multiple-choice licensing test, and that distinction shapes everything below.

Two cautions before the facts. First, the "four domains" you will see listed for this certificate are the four assessment components and their shares of your total weighted scaled score. They are not four science-content areas and not four separate written exams. Second, no single question count or timer describes the whole certification. The question counts and timing below belong to Component 1 only, because Components 2-4 are portfolios built from your own classroom evidence.

If you are brand new to the credential, start with What Is EA/Science Certification? for the big picture, then return here for the numbers. For a slower, step-by-step plan, the EA/Science study guide goes deeper than a cheat sheet can.

The Four Components at a Glance

Your total weighted scaled score is built from four components. Memorize this table first; almost every planning decision flows from it.

Because the weights are about score contribution rather than hours of effort, do not read 15% as "easy" or "quick." Portfolio components demand careful planning of lessons, student work and written commentary. For a candid look at effort, see How Hard Is the EA/Science Exam?

Component 1 Blueprint: Format, Timing and Content Weights

Format and timing

• Selected-response section: approximately 45 items, of which 40 are scored and five are embedded, unscored field-test items. You will not know which are which.
• Constructed-response section: three exercises, titled Data Analysis, Contexts of Science, and Development of Scientific Concepts.
• Split of Component 1: selected responses account for half of Component 1, and the three constructed responses account for the other half.
• Answering time: 60 minutes for selected responses plus 30 minutes per constructed-response exercise, for 150 minutes total.
• Appointment length: about three hours, because the standard appointment also includes the NDA, a tutorial and a break.

Tools and security

A built-in scientific calculator, a constants sheet and a periodic table are provided on screen. Personal calculators and outside references are prohibited. Practice with an on-screen calculator rather than your favorite handheld so the interface is not a surprise.

Selected-response content blueprint

The approximate percentages below describe the selected-response items only. They do not describe all of Component 1 and certainly not the whole certification.

Notice how the content strand is evenly framed across three disciplines: Earth and Space, Life, and Physical Science. Middle-grades teachers often teach one or two of these daily and feel rusty in the third, so audit yourself honestly. The EA/Science exam domains guide unpacks how each strand shows up in practice.

The three constructed-response exercises

• Data Analysis: interpret scientific data and defend conclusions in writing.
• Contexts of Science: connect science ideas to the broader contexts in which they matter.
• Development of Scientific Concepts: show how you would build student understanding of a concept over time.

With only 30 minutes per exercise, rehearse writing a complete, organized response under a timer. The selected-response and constructed-response halves count equally within Component 1, so neglecting writing practice leaves half of that component exposed.

The Nine Science Standards Behind Every Component

The certificate draws on nine Science Standards that describe accomplished practice. They are professional standards, not additional weighted exam domains, so you will not see a percentage next to any of them. Think of them as the lens the assessors use when reading your evidence.

1. Understanding Students
2. Knowledge of Science
3. Curriculum and Instruction
4. Assessment
5. Learning Environment
6. Family and Community Partnerships
7. Advancing Professionalism
8. Diversity, Fairness, Equity, and Ethics
9. Reflection

Portfolio Components 2-4: Classroom Evidence Rules

Components 2, 3 and 4 are classroom-evidence portfolios. They are not taken at a testing center. Instead, you submit artifacts and commentary drawn from your actual teaching. A few facts to plan around:

• Early Adolescence classroom evidence ordinarily requires access to at least six students, with at least 51% of them aged 11-15.
• Component-specific instructions can add or modify requirements, so read each component's directions rather than relying on a general rule.
• Because the evidence comes from your own classroom, your teaching schedule and student population need to line up with the certificate you choose.

That student-age rule is one reason teachers in unusual placements, such as split-grade assignments or part-time roles, should check fit before paying fees. The EA/Science requirements guide walks through eligibility in detail.

Fees, Eligibility and 2026-27 Dates

Fees

The Component 1 retake structure is a meaningful detail: you can retake just the section or exercise that held you back rather than the entire component. For a full budgeting walk-through, see the EA/Science certification cost breakdown.

Eligibility

• An accredited bachelor's degree.
• A valid state teaching license, or satisfaction of state licensure requirements, before registration.
• Three successful years of licensed teaching, verified by June 30 of the third candidacy year.

Timeline limits

• Attempt all four components within three years.
• Achieve certification within five years.

2026-27 cycle dates

• Registration ends February 28, 2027.
• Component 1 testing runs March 1 through June 15, 2027.

Deadlines are the kind of fact that changes, so treat these as your planning anchors and confirm them on NBPTS before committing. Our EA/Science exam dates guide tracks the scheduling details.

Passing Math: Three Thresholds, Not One

Passing is not a single cut score on a single test. To certify, you need eligibility plus all three of the following:

1. An assessment-center unweighted average of at least 1.75 (this is Component 1's side of the ledger).
2. A portfolio unweighted average of at least 1.75 (Components 2-4).
3. A total weighted scaled score of at least 110.

Because the total weighted score applies the 40/15/30/15 weights, a strong showing in a heavy component can offset a weaker showing in a light one, provided you still clear both unweighted averages. Our EA/Science passing score explainer covers the mechanics, and the pass rate article explains why published figures need careful interpretation.

Sequencing Your Prep Around the Weights

You do not need a generic study system here; you need an order of operations that respects how this certificate is built. One reasonable sequence for a candidate working through all four components:

Why this order? Portfolio evidence is tied to your teaching calendar and cannot be manufactured at the last minute, whereas Component 1 can be scheduled flexibly within its testing window. For question-style practice on the content side, the EA/Science practice tests on the main site let you drill the selected-response strands.

After You Certify: Maintenance of Certification

Initial certification is not permanent. EA/Science is maintained every five years through Maintenance of Certification (MOC), a two-component portfolio based on two Professional Growth Experiences. A successful MOC extends certification another five years. The MOC fee is $495 plus the $75 registration.

Keep MOC separate from initial certification in your head. They have different structures and fees, and MOC success statistics are not initial EA/Science exam pass rates. Likewise, EA/Science is distinct from the Adolescence and Young Adulthood science certificate, so do not mix their requirements or materials.

If you are weighing whether the investment pays off, read Is the EA/Science Certification Worth It? and the salary guide; compensation effects vary by state and district, so look at your own local schedule. Middle-grades science teachers can also explore EA/Science jobs for where the credential carries weight. When you are ready to test your recall, try the practice questions at EA/Science Exam Prep.
