Curriculum Development and Adoption of Instructional Materials - 2120

The Board recognizes its responsibility for the improvement and growth of the educational programs of the District. Curriculum and curriculum materials will be evaluated, adapted and developed on a continual basis and in accordance with a plan for curriculum improvement. Instructional materials will be selected to ensure alignment with State learning standards and enable all students to master foundational skills and knowledge to achieve college and career readiness.

The Superintendent, or designee, will establish procedures for core, supplemental and intervention material selection and adoption using criteria around evidence-based practices. The Superintendent will establish procedures which provide for involvement of community representatives and staff members at appropriate times and any suggested changes that should be made as a result of the curriculum review.


For the purpose of Board Policy 2120 and Procedure 2120-P, the following definitions will apply:

Instructional Materials are all materials designed for use by students and their teachers as learning resources to help students to acquire facts, skills, and/or to develop cognitive processes. These instructional materials, used to help students meet State learning standards, may be printed or digital, and may include textbooks, technology-based materials, other educational media, and assessments. They may carry different licensing types from open to all rights reserved. For the purposes of this policy, there are five categories of instructional materials:

Core Instructional Materials are the primary instructional resources for a given course. They are District-approved and provided to all students to help meet learning standards and provide instruction towards course requirements. Core instructional materials are intended for use District-wide by every teacher of the curriculum area with every student each year.

Supplemental Materials are used in conjunction with the core instructional materials of a course. These items are used regularly to support, extend, and enrich core instructional materials to meet the needs of students, but are not intended to supplant the core instructional materials. They include, but are not limited to, books, periodicals, visual aids, video, sound recordings, computer software and other digital content.

Intervention Materials are designed to support strategic or intensive intervention for students who are at risk of not meeting established learning standards. Intervention materials are used with students to accelerate progress toward particular learning goals based on systematic assessment, decision-making, and progress monitoring.

Temporary Materials are those items used in conjunction with the core instructional materials of a course that are of interest or value for a short period of time and are chosen within District-established guidelines. They are not intended to supplant the adopted curriculum nor be used on a regular instructional basis. Examples might include timely articles from relevant, reliable sources, websites, or news broadcasts.

Library Materials are materials that make up the school library collection intended for students to use independently to support curriculum through reading, research, study and for recreational reading. Selection of library materials is an expectation of the professional teacher librarian in cooperation with the professional staff.

The Instructional Materials Committee is the body that makes core instructional materials adoption recommendations to the School Board based on Superintendent-established procedures.

Course Design is the process that includes identifying and sequencing essential content supporting students' skill development towards State learning standards. Course design involves providing appropriate instructional materials, professional development, and support systems for teachers as they implement the course.

New Courses

The Superintendent or designee will establish procedures for course design that provide for the regular review of selected content areas and implementation of any suggested changes, and for the involvement of community representatives and staff members at appropriate times. All new courses or major modifications to existing courses must be approved by the Superintendent prior to implementation. The Superintendent, in turn, will inform the Board before the new course or major revision to an existing course is implemented unless otherwise provided by this policy.

Selection and Adoption of Instructional Materials

The Board is legally responsible for the approval of all core instructional materials used in the District. The responsibility for examining, evaluating and selecting all materials is delegated to the professional staff and reviewed by appropriate committees of the District. Textbooks and other required instructional materials identified as core materials will be approved by the Board prior to their use in the schools except for trial-use. Pilot materials may be authorized by the Superintendent or designee for a short-term duration and prior to Board adoption.

Criteria for Selection and Adoption of Instructional Materials

In selecting instructional materials, the staff will review educational research, District Goals, and State and Federal standards. All instructional materials will be selected in conformance with the following:

  1. applicable State and Federal standards and laws,
  2. procedures established by the Instructional Materials Committee which address the criteria detailed in the corresponding Procedure 2120-P
  3. stimulate growth in higher order thinking skills and place emphasis on cognitive demand,
  4. based on student needs and evaluated by student performance,
  5. reflect the community expectations, social trends and workplace expectations,
  6. present objectively the concerns of racial, ethnic, religious and cultural groups, both historic and current and without gender bias, and
  7. eliminate bias pertaining to sex, race, creed, religion, color, national origin, age, honorable discharged veteran or military status, sexual orientation including gender expression or identity, the presence of any sensory, mental, or physical disability, or the use of a trained dog guide or service animal in all textbooks and instructional materials including reference materials and audio-visual materials.

The Superintendent or designee will ensure that a listing of all core adopted material used within the District curriculum is maintained in the District and is available for public review, either in person or online.

The intent of the Board is that the Superintendent delegate responsibility for examining, evaluating, and selecting supplemental materials to the professional staff of the District.

Supplemental materials that are selected for District-wide use or to be included on the District-approved novel list are to be approved by the Instructional Materials Committee. Staff will rely on reason and professional judgment in the selection of high quality supplemental materials that align to State learning standards and are appropriate for the instructional program and developmental level and interests of their students.
