Assessment plays several important roles in the York Schools:

      • Assessments provide information on individual student academic growth and evidence toward graduation.
      • Assessment data collected in classrooms, through diagnostic tests and state assessments, inform student placement in learning support, enhancement and acceleration opportunities.
      • Assessment results guide the York School Department in curricular and programmatic review and revision.
      • Student assessment results serve as one measure of accountability to the community of York.

Individual student achievement is documented and communicated through class grades, report cards, student and parent conferences and frequent home-school communication.The York School Department uses PowerSchool, an electronic grade portal. All parents at the middle and high school levels can access student progress information electronically through this portal.

The York School Department supplements classroom-based information with:

      • The STAR Assessments - computer-delivered assessments administered twice each year to students in grades Kindergarten through nine that provide rich sources of data on student growth in reading, language usage and mathematics. Some students are assessed more frequently, to allow teachers to more closely track student progress.
      • PSAT - A test which measures English Language Arts/Literacy and Mathematics for grade ten and eleven students.
      • The MECAS, Maine Comprehensive Assessment System - This includes the following state required assessments to measure the statewide progress of student achievement in English Language Arts/Literacy, Mathematics, and Science.
      • EmPowerME - English language arts and mathematics in grade 3-8
      • SAT - English Language Arts and Mathematics for third-year high school students
      • Science MEA - Science at grades 5, 8, and 11.
      • Some students whose special education plans (IEPs) establish the need for individualized progress documentation are provided with an alternate assessment for English Language Arts/Literacy and Mathematics and for Science.

Accreditation through the New England Association of Schools and Colleges provides another level of community accountability.

Dyslexia Screening - Maine law requires school administrative units to screen students for dyslexia. In 2016-17 all York students in grades K-2 were screened. The school district annually updates this screening for all kindergarten students, and students new to the district in grades 1 and 2. Data from the STAR, BAS, phonological awareness/phonics assessment, spelling inventory/letter writing, sentence dictation, and rapid naming are used as part of the screening process.
