Bilingual Assessment Team


The Bilingual Assessment Team (BAT) is a multilingual unit designed to collaborate with schools' Individualized Education Program (IEP) teams to assess and interpret data from English Language Learners who have or are suspected of having an educational disability.

BAT is comprised of bilingual instructional specialists, school psychologists, and speech/language pathologists. The BAT unit office is located at Rocking Road Horse Center.

What We Do

Members of the BAT unit collaborate with school teams and families to support collaborative problem solving and address the needs of English Language Learners who are suspected of having educational disabilities.

The BAT staff members use the linguistic and cultural knowledge, skills, and abilities of its members to make complex special education procedures understood by parents from diverse cultural and linguistic backgrounds.

The BAT staff members use a variety of standardized instruments, informal measures, rating scales, and observations to collect data and make a valid assessment of the student's learning needs.

The BAT unit provides the following services to local school Educational Management Teams (EMTs) and IEP teams, as appropriate:

  • Language dominance determinations
  • Psychological assessments
  • Educational assessments
  • Speech-language assessments (Spanish only)

All referrals to the BAT unit must be made using one of the following forms:

When is a student referred to the BAT?

The EMT staff members, including the ESOL teacher, should have implemented systematic interventions and documented their effectiveness before referring an English Language Learner (ELL) to the BAT unit. The appropriate ESOL instructional specialist can provide advice and suggestions during this process. Following implementation of interventions, students who do not show appropriate progress and students who show evidence of a disability should be referred to the IEP Team. The EMT should request completion of a language dominance assessment of ESOL level 3 or 4 students before the screening IEP team meeting is held.

Action Steps for ELL students prior to referral for IEP screening:

  • Initiate Collaborative Problem Solving
  • Implement interventions/accommodations with integrity
  • Use data-based decision making to determine if the intervention is successful
  • Return to Collaborative Problem Solving/EMT when interventions are not successful to determine next steps

What happens next?

  • Refer to IEP Team and BAT using the appropriate BAT Referral form.
  • BAT will assign an instructional assessment specialist to determine ESOL level 3 or 4 student's dominant language.

What is a language dominance determination?

The main purpose of a language dominance determination is to determine the appropriate language(s) for testing if evaluation is recommended by the IEP team. There are essentially three possible outcomes from language dominance assessment:

  1. First Language Dominant: All testing should be done bilingually. Educational and psychological assessments will be done by the BAT. Speech-language assessments in Spanish will be done by the BAT except in special circumstances dictated by the Speech and Language Programs office. Speech-language assessments in languages other than Spanish will be done by school-based personnel with an interpreter.
  2. English Dominant: All testing will be conducted in English by school-based personnel.
  3. Mixed Dominant: Typically, a student who demonstrates mixed language dominance is more competent academically in English than in his or her first language but the student may understand and communicate better in his or her first language. For this reason, the educational assessment is done by local school personnel in English, but the psychological and speech-language assessments may be completed bilingually or with an interpreter.

What happens after the screening IEP meeting?

  1. If an evaluation has been recommended, testing is assigned to a BAT staff member.
  2. If the school is requesting BAT complete assessments(s), the school personnel must send a complete BAT referral. Send the correct BAT Referral form and packet with all necessary documents to the BAT unit. Referrals should be sent to the BAT unit as soon as possible after the IEP meeting.
  3. A school representative should contact the BAT unit 3 work days after the referral has been mailed to the BAT unit to confirm its receipt.
  4. After the BAT unit receives the referral, the appropriate personnel will be assigned to conduct the requested assessments.
  5. When needed, school personnel should obtain an interpreter for the Evaluation IEP meeting.
  6. BAT assessments will be reviewed at the Evaluation IEP meeting. As timelines and scheduling permit, the BAT psychologist assigned to a case may attend the Evaluation IEP meeting; otherwise assessments should be reviewed by members of the school IEP team.
