Decoding Indiana's IAS: A Teacher's Guide to Reading and Using Standards for Lesson Planning

Why Understanding IAS Structure Actually Matters

I spent my first year in Indiana classrooms feeling like I was decoding a foreign language when I looked at standards. The abbreviations, the decimal points, the numbered categories—it all felt unnecessarily complicated. Then I realized something: once you understand how Indiana Academic Standards (IAS) are organized, they become a roadmap instead of bureaucratic noise. That's what this guide is for.

Breaking Down the IAS Code

Let's look at a real example from the drama standards: TH:Cn12.1.1.b

Here's what each part tells you:

• TH = The subject area. In this case, Theatre. You'll also see standards coded as VA (Visual Arts), MU (Music), and DA (Dance).
• Cn = The standard category. Theatre has three categories: Cr (Create), Pr (Perform), Re (Respond), and Cn (Connect). This particular standard falls under "Connect," meaning it's about relating artistic ideas to broader contexts.
• 12 = The grade band. Indiana organizes K-12 into bands: K-2, 3-5, 6-8, and 9-12. This one targets grades 9-12.
• 1 = The standard number within that category for that grade band. It's the first "Connect" standard for high school theatre.
• 1 = The sub-standard. Some standards break into lettered components (a, b, c).
• b = This is the specific benchmark you're looking at. The "b" means this is the second component within standard 1.

So when you see TH:Cn12.1.1.b, you're looking at: Theatre, Connect category, grades 9-12, standard 1, component b, which reads: "Collaborate on the creation of a short scene based on a fictional literary source in a guided drama experience."

Understanding the Hierarchy: Why It Matters for Planning

Indiana's IAS are organized in layers, and understanding this hierarchy saves planning time. The broadest layer is the standard itself. TH:Cn12.1 is the full standard: "Research." This is your big-picture learning target.

Beneath that sit the more specific benchmarks with letters. TH:Cn12.1.1.a asks students to "Identify similarities and differences in stories from one's own community in a guided drama experience." The b component requires collaboration on creating a scene from literature.

When you're planning a unit, start at the standard level to understand what students should ultimately know and be able to do. Then use the lettered components to scaffold instruction and create specific learning objectives for individual lessons or activities.

How to Actually Use Standards When Planning Units

Here's my practical process:

Step 1: Identify Your Target Standards

Pull the standards for your grade level and content. If you're teaching high school drama and want students to understand how theatre connects to literature and culture, you'd likely target standards under the "Connect" category (Cn) for grades 9-12. Write these down—all of them. You might have 8-10 standards you want to address across a semester.

Step 2: Cluster Related Standards

Look for natural connections. In drama, you might notice that TH:Cn11.1.1.a (applying skills from different art forms) pairs well with TH:Cn12.1.1.b (collaborating on scenes from literature). These could form one thematic unit about interdisciplinary storytelling. This clustering prevents standards from feeling like random checkboxes and creates coherent learning experiences.

Step 3: Unpack Each Standard into Student-Friendly Language

The official wording is precise but not always accessible to students. Translate it. For TH:Cn12.1.1.b, you might write: "I can work with classmates to create a short dramatic scene based on a story I've read." Post these in your classroom. Students should know what they're learning and why.

Step 4: Design Assessments Before Lessons

This is where standards become actionable. If the standard requires students to "collaborate" and "create," your assessment needs to measure both. A collaborative creation project (not an individual test) actually assesses the standard. Too many teachers write standards on their plans but then assess something completely different. Let the standard language guide your assessment design.

Step 5: Plan Backward to Learning Activities

Once you know what students need to do (the assessment), plan the lessons and activities that build toward that. If your assessment is creating a scene from literature collaboratively, you need lessons on analyzing literature dramatically, understanding scene structure, and practicing collaboration skills. Each lesson targets pieces of the standard.

A Word About ILEARN and Standards Alignment

Indiana's ILEARN assessment measures whether students have met the IAS. When standards are well-taught, ILEARN results improve naturally—there's no need to "teach to the test." The test measures the standards; the standards define what matters. Focus on deep, standards-aligned instruction, and assessment results follow.

Your Next Step

Pull your grade level's IAS for your subject. Pick one standard. Decode the code. Read the full benchmark. Then ask yourself: "What would I need to see a student do to prove they've met this standard?" That question transforms a string of letters and numbers into a real learning target. That's when standards stop feeling like compliance and become genuinely useful planning tools.
