The Technology Team Assessment Process (TTAP) showed low interrater reliability for students with learning disabilities, indicating it needs further development before confident use in assessments.

Area of Science:

  • Educational Psychology
  • Assistive Technology Research
  • Special Education

Background:

  • The Technology Team Assessment Process (TTAP) is a tool used to evaluate students.
  • Assessing students with learning disabilities requires reliable and valid tools.
  • Interrater reliability is crucial for consistent assessment outcomes.

Purpose of the Study:

  • To evaluate the interrater reliability of the Technology Team Assessment Process (TTAP).
  • To determine the consistency of TTAP assessments when used by different raters.

Main Methods:

  • Five trained raters independently assessed videotaped TTAP evaluations of students aged 9-12 with learning disabilities.
  • Raters used TTAP recording forms and made assistive technology recommendations.

  • Interrater reliability was analyzed using intraclass correlation coefficients.

    • Main Results:

    • Only one of the four investigated sections of the TTAP demonstrated acceptable interrater reliability.
    • The majority of the TTAP sections showed insufficient agreement between raters.
    • Assistive technology recommendations varied among raters.

    Conclusions:

    • The current version of the TTAP lacks sufficient interrater reliability for assessing students with learning disabilities.
    • The TTAP requires significant further development and rigorous testing before clinical application.
    • Concerns exist regarding the consistent application and interpretation of TTAP assessments.
