As an educator and instructional coach, I’ve come to realize data isn't just a tool, it's a lifeline for understanding and meeting the unique needs of our students. For those of us working with multilingual learners, data-driven instruction (DDI) is even more essential. It allows us to see beyond test scores and academic progress, recognizing our students as individuals with diverse linguistic and cultural backgrounds. This approach is at the heart of equity in education.

As an instructional coach supporting teachers of multilingual learners, my role is to demystify data and make it meaningful. I help teachers connect data to students' language development, cultural experiences, and unique strengths. We don’t just look at numbers, but we analyze data within the broader context of student growth. Some of the key data we review include formative assessments, classroom observations, language proficiency scores, and even anecdotal notes to understand how our multilingual learners are progressing.
Why DDI Matters for Multilingual Learners

For multilingual learners, data is more about tracking language acquisition and identifying instructional gaps than measuring academic success alone. I rely on tools like Proficiency Level Descriptors (PLDs) and state assessments to uncover trends in English language development and guide instructional decisions. By studying these patterns, I can support teachers in identifying effective strategies tailored to each student's language proficiency level. Multilingual learners benefit from strategies that target their specific language needs. Data can serve as a roadmap, showing exactly where each student is in their academic and language-learning journey.
Why DDI Matters for Teachers and Coaches
Effective instructional coaching for data use follows four key principles: Clarify what data is and isn’t, keep things simple, use a data protocol, and repeat the process (NWEA, 2024).
I collaborated with teachers to make data actionable by targeting specific language needs of multilingual learners. We used data analysis protocols to identify instructional strategies that are both equitable and effective. By pairing language proficiency scores with formative assessments, we created individualized language plans aligned with content progressions and PLDs.
I remember working with a team of 7th-grade science teachers who were struggling to differentiate instruction for their multilingual learners during a body systems unit. Through data analysis, we discovered students could correctly identify body systems when given pictures but struggled when scenarios required them to match functions using word phrases. By aligning PLDs with formative assessments, we created targeted vocabulary scaffolds that immediately boosted student comprehension and content mastery.
This approach allowed us to tailor instruction, ensuring that multilingual learners received the scaffolds and challenges they needed to succeed:
For students who were developing foundational language skills, we provided targeted scaffolding to build academic vocabulary and comprehension.
For advanced multilingual learners, we designed opportunities that expanded their critical thinking and increased their engagement with complex tasks.
The Bottom Line
Data-driven instruction is a cornerstone of equity for multilingual learners. It empowers educators to move beyond assumptions, make informed decisions, and design personalized learning experiences that truly honor the strengths and needs of every student.
Ready to Embrace Your Data-Driven Coaching Practice?
If you’re an instructional coach working with teachers of multilingual learners, you play a crucial role in making data meaningful and actionable. I encourage you to take these key steps to guide teachers' use of data:
Strengthen your own learning about data-driven instruction
Guide teachers in taking action with data
Foster a collaborative culture around data
By embracing data-driven practices, we can create classrooms where language, culture, and identity are valued and celebrated. Let’s take this journey together!!!
