Everything you need to know about IEPs

Bracha HahnBlog

If you have students with special needs in your classroom, you’ve likely come across the terms accommodations and modifications. These are cornerstones of Individualized Education Programs (IEPs) and 504 plans, and understanding the difference between them is one of the most practical things a teacher can do to support every learner.

This post breaks down what IEPs are, how accommodations and modifications differ, and what implementation looks like in a real classroom.

What is an IEP?

An Individualized Education Program (IEP) is a legally binding document developed for students who qualify for special education services under the Individuals with Disabilities Education Act (IDEA). It outlines a student’s present levels of performance, annual learning goals, and the specific supports and services the school will provide.

As a classroom teacher, you are part of the IEP team. That means you play a direct role in both implementing and informing the plan.

Research consistently shows that when general education teachers are actively involved in the IEP process, students with disabilities experience better academic outcomes and stronger school connectedness (Kurth & Mastergeorge, 2010).

Accommodations vs. modifications: what’s the difference?

This is where a lot of confusion happens, and it matters.

Accommodations change how a student learns or demonstrates knowledge but not what they are expected to learn. The standards stay the same. A student receiving accommodations is still working toward the same goals as their classmates.

Examples of common accommodations:

  • Extended time on tests.
  • Preferential seating.
  • Audio versions of texts.
  • Reduced visual distractions.
  • Oral responses instead of written.

Modifications change what a student is expected to learn or demonstrate. The content or performance expectations are adjusted to reflect the student’s individual abilities.

Examples of common modifications:

  • Shortened assignments.
  • Alternate assessments.
  • Simplified reading materials.
  • Reduced number of test questions.

The key distinction: with accommodations, grading remains the same as for other students. With modifications, grading may reflect a different set of expectations.

The four types of accommodations

IEP accommodations typically fall into four categories:

PRESENTATION accommodations change how information is delivered. A student with a visual impairment might receive materials in Braille or large print. A student with processing challenges might benefit from visual cues or step-by-step instructions.

RESPONSE accommodations change how students show what they know. A student with fine motor difficulties might type instead of write. Others might use a scribe, give oral responses, or use assistive technology.

SETTING accommodations adjust the environment. A student with ADHD might be seated away from high-traffic areas. A student with sensory sensitivities might have access to a quiet space with calming tools.

SCHEDULE accommodations adjust timing. Extended time on assessments is the most common example. Frequent breaks between tasks are another, particularly for students with autism or anxiety.

What the research says

A 2024 peer-reviewed study found that students with well-implemented IEPs showed a significant improvement in academic performance scores compared to the prior year, underscoring the impact of plans that are carefully aligned to individual student needs (Srivastava, 2024).

A 2023 meta-analysis published in Educational Psychology Review found large positive effects on teacher knowledge and moderate positive effects on student behavior when teachers received professional development focused on inclusive education practices — the kind of training that supports confident, effective IEP implementation (Rott et al., 2023).

Research also consistently shows that when families and educators partner effectively around the IEP process, the quality of services and supports improves for students with disabilities (Freeman & Jacob Kirksey, 2022).

Practical tips for classroom teachers

  • Read the IEP before school starts. Know your students’ goals, not just their accommodations list.
  • Communicate with the special education team. You don’t have to figure this out alone.
  • Document what you’re doing. Brief notes about how accommodations are implemented protect you and help the team make good decisions at annual reviews.
  • Focus on access, not advantage. Accommodations level the playing field; they don’t give students an unfair edge.
  • Revisit and reflect. If something isn’t working, say so. The IEP is a living document.
