Which Grade Levels and Subjects Does Curriculum Associates Cover?

Curriculum Associates covers grades K–8 through its i-Ready programs (assessment, personalized instruction, core literacy, and mathematics), grades 6–8 science through Stile Science, and English Learner support across grade levels through Ellevation. The exact grade range and subject mix depends on which program a school adopts, so the practical answer is to match the program to the grade band and subject you need.

Program-by-Program Coverage

i-Ready: K–8 Assessment, Instruction, Literacy, and Math

i-Ready is the broadest of the three. It connects assessment with both core and supplemental instruction, so a school can use it to measure where students are and then act on that data. The subject coverage named in the program description is literacy and mathematics, alongside personalized instruction and assessment for grades K–8.

This makes i-Ready the option to look at if you need a single portfolio spanning elementary and middle school in reading and math. The connection between assessment and instruction is the core design idea: data is meant to translate into instructional next steps rather than sit in a separate reporting tool.

Stile Science: Grades 6–8, Built for the NGSS

Stile Science is a narrower fit by design. It covers grades 6–8 science and is built for the Next Generation Science Standards, with customization available. If your district teaches middle school science and follows NGSS, this is the relevant program; if you need elementary science or high school science, it is not the match based on the available program description.

Ellevation: English Learner Support Across Grade Levels

Ellevation is organized around multilingual student success rather than a single grade band. It provides a unified ELD platform with data, professional learning, and instructional tools. The program description notes it serves nearly half the nation's English Learners, which signals broad adoption rather than a narrow grade restriction. For a school planning EL support, Ellevation is the piece that sits alongside core instruction rather than replacing it.

Subject Areas Beyond the Core Programs

The site also organizes resources and instructional topics that extend past the three flagship programs, including:

• Middle school algebra readiness
• Core math
• Data-driven instruction
• Differentiating instruction
• Reading instruction
• RTI/MTSS
• Science of Reading

These topic areas indicate where the curriculum and instructional design work is concentrated. They are useful for judging fit: for example, a district building an RTI/MTSS framework or shifting toward Science of Reading–aligned literacy instruction will find those themes reflected in the materials and resources.

How to Decide Which Program Fits

Use the grade band and subject as the first filter:

1. Grades K–8, reading and math, with assessment: start with i-Ready.
2. Grades 6–8 science under NGSS: look at Stile Science.
3. English Learners at any grade level: look at Ellevation.

A school serving K–8 typically combines programs rather than choosing one — i-Ready for literacy and math, Stile Science for middle school science, and Ellevation for multilingual learners. Confirming the exact grade and subject configuration for your school is best done through the ordering and support channels listed on the site, since customization is part of how these programs are positioned.
