Need a Proven Solution for English Learners?

The SIOP® Model establishes an effective instructional approach to support content and language objectives. Research studies on SIOP®  prove its effectiveness in real-world classroom settings at all grade levels, from elementary through high school. Teachers trained in using the SIOP®  model have been shown to significantly improve scores on language tests versus teachers who had no training. Watch a video or browse through the research to see how the SIOP®  Model can help your teachers and students.

Got a Question? We’ve Got the Answer.

Who can implement the SIOP® Model?

Pre-K, elementary, and secondary subject area teachers, reading/language arts and English teachers, resource teachers, coaches, specialists, special educators, community college, and university professors can and do implement the SIOP® Model. It may be part of a general education program, an ELL program, a late-exit bilingual program, a dual-language/two-way bilingual immersion program, a newcomer program, a sheltered program, or even a foreign language immersion program.

Is the SIOP® Model only for English learners?

No. The SIOP® Model has also been validated with native English speaking students, both general education and special education students, and former English learners. When teachers implement the thirty features consistently, all subgroups of students, including students receiving special education services, demonstrate academic gains.

What if I have students who can't speak any English? Will SIOP® help?

It will certainly help, but it's not enough. Beginning speakers, or newcomers, need intensive English instruction provided by an ELL or ELD teacher, in addition to effective SIOP® instruction the rest of the day. If newcomer programs are not available, SIOP® instruction provides students with the best opportunity to comprehend lessons.

Who should receive professional development with the SIOP® Model?

Anyone who will be working with English learners, including teachers, support personnel, instructional assistants, and administrators.

In addition, an overview of the SIOP® Model is beneficial for School Board members and district-level administrators, so everyone is starting on the "same page" with the same ultimate goal.

Is the SIOP® Model compatible with the Common Core State Standards?

Yes. The Common Core State Standards can be used to guide content and language objectives in English language arts and mathematics. The fact that the Common Core State Standards include listening and speaking standards, when a number of state English language arts standards do not, is beneficial to teachers working with English learners.
