Assessment Fundamentals
Assessment is the systematic collection and analysis of information about student learning. Effective assessment informs instruction, documents progress, and supports student growth.
Types of Assessment
Diagnostic assessment occurs before instruction to identify prior knowledge, skills, and misconceptions. Pre-tests, learning inventories, and KWL charts serve diagnostic purposes.
Formative assessment occurs during instruction to monitor learning and adjust teaching. Exit tickets, observations, questioning, and quizzes provide ongoing feedback. Formative assessment is assessment for learning.
Summative assessment occurs after instruction to evaluate mastery. Unit tests, projects, and standardized assessments measure achievement. Summative assessment is assessment of learning.
Benchmark assessments measure progress toward standards at specific intervals throughout the year. These interim assessments help predict performance on summative measures and identify students needing intervention.
| Type | When | Main purpose | Examples |
|---|---|---|---|
| Screening | Start of year, then periodically | Find students who may be at risk | Brief universal literacy or math screeners |
| Diagnostic | Before or during instruction | Pinpoint specific skills and misconceptions | Phonics inventory, spelling inventory, pre-test |
| Formative | During instruction | Adjust teaching while learning is happening | Exit tickets, observation, whiteboards, conferences |
| Progress monitoring | Every 1–2 weeks during intervention | Check whether an intervention is working | Oral reading fluency probes, math fact probes |
| Benchmark / interim | Several times a year | Track progress toward standards | District benchmark tests |
| Summative | End of a unit or year | Judge mastery | Unit test, project with rubric, state test |
Assessment Characteristics
Validity refers to whether an assessment measures what it intends to measure. Content validity ensures coverage of intended learning objectives. Construct validity ensures the assessment measures the underlying skill or knowledge.
Reliability refers to consistency of results. A reliable assessment produces similar results under consistent conditions. Test-retest reliability measures consistency over time. Inter-rater reliability measures consistency among different scorers.
Bias occurs when assessment items disadvantage certain groups based on characteristics unrelated to the measured construct. Culturally responsive assessment considers diverse backgrounds and experiences.
Assessment Methods
Selected-response items include multiple-choice, true-false, and matching. These formats efficiently assess recognition and recall but may not capture complex thinking.
Constructed-response items require students to generate answers. Short-answer and essay questions assess deeper understanding and application.
Performance assessments require students to demonstrate skills through authentic tasks. Portfolios collect student work over time to document growth. Rubrics provide criteria for evaluating performance quality.
Using Assessment Data
Data-driven instruction involves analyzing assessment results to inform teaching decisions. Item analysis identifies concepts requiring reteaching. Error analysis reveals patterns in student misconceptions.
Response to Intervention (RTI) uses assessment data to provide tiered support. Tier 1 includes high-quality core instruction. Tier 2 provides targeted small-group intervention. Tier 3 offers intensive individualized intervention.
| Tier | Who | What it looks like |
|---|---|---|
| Tier 1 | All students (about 80% should succeed here) | High-quality, research-based core instruction with differentiation and universal screening |
| Tier 2 | Students below benchmark (about 15%) | Targeted small-group intervention several times a week, progress monitored |
| Tier 3 | Students not responding to Tier 2 (about 5%) | Intensive, individualized intervention; may lead to a special education evaluation |
