Reading screenings
WHAT
- In phonological awareness, diagnostic tools determine a student’s ability to hear, segment, blend, and manipulate sounds in spoken words, which is foundational for decoding.
- In phonics, they measure knowledge of letter-sound correspondences, decoding of single-syllable and multisyllabic words, and spelling patterns.
- Fluency screening evaluates accuracy, rate, and prosody during oral reading, helping teachers understand whether a student reads smoothly enough to support meaning-making.
- Vocabulary diagnostics assess both expressive and receptive word knowledge, as well as understanding of word relationships and morphology.
- Comprehension measures examine a student’s ability to understand, interpret, and analyze text, including literal recall and higher-order thinking skills.
WHY
By pinpointing specific skill gaps within these five areas, diagnostic screening provides actionable data that guides explicit, direct instruction. Rather than relying on broad assumptions, teachers can target instruction systematically—modeling skills clearly, providing guided practice, offering corrective feedback, and monitoring progress. This precision ensures that interventions are aligned to student needs, increase instructional effectiveness, and helps prevent ongoing reading difficulties by addressing the root causes early and intentionally.

Math Screenings
WHAT
- In number and operations, screening reveals understanding of number sense, place value, magnitude, counting principles, computational fluency, and the ability to perform and explain addition, subtraction, multiplication, and division. It can uncover whether difficulties stem from weak conceptual understanding, inefficient strategies, or lack of automaticity with basic facts.
- In algebraic thinking, diagnostic tools assess a student’s ability to recognize patterns, understand relationships between quantities, use unknowns, interpret equations, and apply properties of operations. These assessments help determine whether a student can move beyond procedural computation to reasoning about mathematical relationships.
WHY
The importance of diagnostic screening lies in its ability to guide explicit, targeted instruction: teachers can address misconceptions directly, build conceptual understanding through concrete and visual models, and systematically develop procedural fluency and reasoning skills. By identifying precise areas of need early, diagnostic screening prevents gaps from widening, supports differentiated intervention, and strengthens the foundational skills necessary for success in more advanced mathematics.
