When a student has an Individualized Education Program (IEP), the supports written in that document are not optional. They are required services designed to help the student access a free and appropriate public education.
But one of the most common questions educators ask is:
Who is responsible for what in an IEP?
Is it the special education teacher?
Is it the general education teacher?
Or is it both?
The short answer is both.
IEP implementation is a shared responsibility. When everyone understands their role, services are implemented more consistently, and students receive the support they need throughout the school day.
Understanding how responsibilities are typically divided can help reduce confusion and strengthen collaboration between teachers.
The Special Education Teacherโs Role in the IEP
Special education teachers often serve as the instructional leaders and case managers when it comes to IEP implementation. Their training focuses on individualized instruction, adapting curriculum, and analyzing student progress.
One of their primary responsibilities is delivering Specially Designed Instruction (SDI). SDI refers to instruction that is specifically adapted to address a studentโs unique learning needs and help them access the general education curriculum.
Teaching Specially Designed Instruction
Special education teachers are typically responsible for introducing and explicitly teaching SDI connected to a studentโs IEP goals.
This might include things like explicit reading instruction, social skills instruction, behavior regulation strategies, executive functioning supports, or targeted math interventions.
Because SDI is individualized and directly tied to IEP goals, it is usually planned and initially taught by the special education teacher.
Managing the IEP
In many schools, the special education teacher also serves as the IEP case manager. This means they help coordinate services and make sure the IEP is being implemented as written.
Case management responsibilities may include tracking service minutes, organizing IEP meetings, ensuring documentation is complete, and helping other teachers understand the supports listed in the IEP.
Supporting SDI Across Classrooms
Once students learn a new strategy or skill during SDI instruction, they need opportunities to use it in other environments throughout the school day.
General education teachers often reinforce these strategies in the classroom while the special education teacher provides guidance and support.
For example, a student might learn a writing organizer during small group instruction with the special education teacher and then use that same organizer when completing assignments in the general education classroom.
This type of collaboration helps students apply their skills across settings.
Monitoring Progress Toward Goals
Another key responsibility of the special education teacher is monitoring progress toward IEP goals.
This may involve collecting data during instruction, analyzing student performance, adjusting interventions when needed, and reporting progress to families.
While the special education teacher often organizes and tracks progress data, the information frequently comes from multiple classroom settings.
The General Education Teacherโs Role in the IEP
Many students with IEPs spend most of their day in general education classrooms. Because of this, general education teachers play a critical role in implementing the IEP.
A common misconception is that the IEP only applies during special education services. In reality, the IEP must be followed in any setting where the student receives instruction.
Implementing Accommodations
General education teachers are responsible for providing the accommodations listed in the IEP while the student is in their classroom.
Accommodations help students access learning without changing the academic expectations. These supports may include extended time on tests, preferential seating, audio versions of text, graphic organizers, or reduced distractions during assessments.
If an accommodation appears in the IEP, it must be implemented consistently.
Implementing Modifications
Some students may also receive modifications, which change the expectations or complexity of the work.
This might involve shortened assignments, simplified reading material, or alternate grading expectations.
Special education teachers often help design these modifications, but general education teachers typically implement them within the context of their classroom instruction.
Reinforcing SDI Strategies
General education teachers also help students apply the strategies they learn during SDI instruction.
For example, a student may learn a comprehension strategy during reading intervention and then practice that strategy while completing a science or social studies assignment.
When teachers reinforce these strategies consistently, students are more likely to generalize the skills they are learning.
Responsibilities That Are Shared
While certain responsibilities fall more heavily on one teacher than another, many aspects of IEP implementation are shared.
Collaboration between teachers is essential to ensure that students receive consistent support throughout the day.
Data Collection
Both general education and special education teachers often collect data related to student progress.
A special education teacher may gather information during intervention sessions, while a general education teacher may track how the student performs during classroom assignments or assessments.
Looking at both sets of data together provides a more complete picture of the student’s progress.
Parent Communication
Communication with families is also a shared responsibility.
Special education teachers often communicate about progress toward IEP goals, while general education teachers may provide updates about classroom performance, assignments, or behavior.
When communication is consistent and collaborative, families receive a clearer understanding of how their child is doing.
Monitoring Accommodations and Supports
Both teachers should monitor whether the supports listed in the IEP are effective.
This might involve discussing whether accommodations are being used consistently, whether students are becoming more independent, and whether adjustments are needed.
Frequent communication between teachers helps ensure that supports remain appropriate and effective.
Why Collaboration Matters
IEP implementation works best when educators approach it as a team effort.
Students move through multiple classrooms, subjects, and environments throughout the day. When teachers work together, they can create consistency in expectations and support.
Regular check-ins, shared documentation, and open communication make it easier to ensure that the IEP is implemented with fidelity.
When everyone understands their role, the focus can remain where it belongsโsupporting the student.
The Bottom Line
IEP implementation is a shared responsibility.
In most situations, the special education teacher is responsible for introducing and teaching specially designed instruction, managing the IEP, and monitoring progress toward goals.
General education teachers are responsible for implementing accommodations and modifications within their classrooms and reinforcing strategies students learn during SDI.
Both teachers share responsibility for collecting data, communicating with families, and collaborating to support the studentโs success.
When everyone works together and understands their role, students receive the consistent support they need to grow and thrive.
