Our K–12 Services

Our teams bring deep experience in curriculum development, assessment, accessibility, and digital learning, helping partners deliver content that is rigorous, inclusive, and scalable.

 

Curriculum Design

Coherent, standards-aligned curricula built for diverse learning environments.

We design full K–12 curricula that balance instructional rigor, usability, and scalability. Our teams develop programs from scope and sequence through unit and lesson design—ensuring content works across classrooms, digital platforms, and blended environments.

What this looks like in practice:

  • Full-program and course design

  • Scope and sequence development

  • Unit and lesson planning

  • Curriculum refreshes and new editions

  • Alignment-ready program structures

Assessment Writing

Formative and summative assessments that measure learning effectively.

We develop assessments that support instruction and provide meaningful insight into student understanding. Our work spans item writing, rubrics, and assessment systems designed to align with standards and instructional goals.

What this looks like in practice:

  • Formative and summative assessment development

  • Item writing across question types

  • Rubrics, exemplars, and rationales

  • Assessment refreshes and revisions

  • Alignment to standards and learning objectives

Editorial Development

Instructionally sound, age-appropriate content development at scale.

Strong editorial development ensures large K–12 programs feel cohesive and intentional. We manage complexity across authors, grades, and subjects while maintaining accuracy, consistency, and instructional clarity.

What this looks like in practice:

  • Program planning and editorial blueprinting

  • Developmental editing and copyediting

  • Fact-checking and quality assurance

  • Voice and style consistency management

  • SME and contributor coordination

Standards Alignment

Clear alignment to Common Core, state standards, and accessibility requirements.

We embed alignment thinking throughout development rather than treating it as a final compliance step. This approach supports adoption, reduces rework, and increases confidence at launch.

What this looks like in practice:

  • Alignment to Common Core, NGSS, and state standards

  • Correlation documentation and mapping

  • Review and remediation of existing content

  • Support for multi-state and national adoption

Multilingual Content

Culturally responsive content for multilingual and diverse learners.

We develop and adapt K–12 instructional materials to support multilingual learners through translation and transadaptation—preserving instructional intent while ensuring clarity and cultural relevance.

What this looks like in practice:

  • Multilingual content development and adaptation

  • Cultural and linguistic review

  • Coordination across languages and grade levels

  • Quality assurance for translated content

  • Support for dual-language programs

Instructional Design & Learning Experience

Learner-centered design that brings curriculum to life.

We apply learning science and pedagogical best practices to shape how students engage with content. Our instructional design work ensures experiences are age-appropriate, motivating, and instructionally sound.

What this looks like in practice:

  • Pedagogical and learning experience design

  • Course and program templates

  • Learner journey and content mapping

  • Engagement-focused design strategies

  • Iterative testing and refinement

Creative & Digital Media

Engaging digital assets that deepen understanding and motivation.

Our creative teams design media that supports learning—not distraction. From interactive simulations to instructional video, we build assets that clarify concepts and enhance engagement.

What this looks like in practice:

  • Animations and interactive simulations

  • Technical and scientific illustrations

  • Instructional video and multimedia

  • Digital-first asset development

  • Support for STEM and hands-on learning

Technology, Platforms, & Delivery

Scalable delivery across LMS, platforms, and digital environments.

We ensure K–12 content functions smoothly within real instructional ecosystems. Our teams support platform readiness, reusable templates, and delivery at scale.

What this looks like in practice:

  • LMS integration and optimization

  • Platform-ready content outputs

  • Reusable course and content templates

  • UI/UX considerations for learning environments

  • Scalable digital delivery support

Accessibility

Inclusive learning materials designed to meet WCAG and Section 508 standards.

Accessibility is integrated throughout our development process—not retrofitted at the end. We ensure materials are usable, compliant, and instructionally effective across formats.

What this looks like in practice:

  • WCAG- and Section 508–aligned development

  • Accessible instructional materials and assessments

  • Accessibility review and remediation

  • Integration across print and digital formats
