2021 Oregon K-12 Math Standards (CCSS-M-derived Oregon standards, with renamed domains and an added Data Reasoning strand) — Oregon
Students can explain and apply mathematical concepts and interpret and carry out mathematical procedures with precision and fluency. Targets are clusters of the 2021 Oregon K-12 Math Standards; the 2025-26 blueprint draws 10 of the grade 6 CAT's 19 items from these targets — 7 from priority target sets, 3 from supporting. Beginning in grade 6 the CAT has one segment with an embedded Desmos calculator and one calculator-free segment, consistent with Smarter Balanced item specifications. This Grade 6 reporting domain maps to 22 practice skills and 8 representative questions from the playable bank.
2021 Oregon K-12 Math Standards (CCSS-M-derived Oregon standards, with renamed domains and an added Data Reasoning strand) — Oregon
Oregon's statewide summative math test — part of OSAS, the Oregon Statewide Assessment System (the landing slug keeps the legacy OAKS name) — is developed through Smarter Balanced: a computer-adaptive test plus a performance task, organized into the four Smarter Balanced claims. Since aligning to the 2021 Oregon K-12 Math Standards, Oregon publishes its own blueprint rather than the consortium's: Claim 1 assessment targets carry Oregon cluster codes with renamed/regrouped domains (GM geometric measurement and DR data reasoning replace MD and SP; AEE and AFN replace EE and F; grade 7 probability moves to 7.RP.B), each cross-referenced to its former Smarter Balanced letter target, plus new Oregon-developed Data Reasoning targets field tested in 2024-25. Claims 2-4 keep the Smarter Balanced process targets (Claim 4 without the consortium's Target G, and Claim 3 Target G appearing on the grade 6-8 and 11 blueprints only). Claim 1 targets are grouped into priority and supporting target sets with published per-set item counts.
OSAS Summative Mathematics Test Blueprints (2025-26, last updated 12/22/2025): each grade's CAT draws 10 Claim 1 items in grades 3-8 (7 from priority target sets and 3 from supporting; 6 and 4 in grade 5) and 13 in grade 11 (9 priority, 4 supporting), 3 items from combined Claims 2 and 4, 4 Claim 3 items, and 2 unscored field-test items — 19 CAT items total in grades 3-8, 22 in grade 11. The performance task adds 4-6 items: 1-2 Claim 2, 0-2 Claim 3, 1-3 Claim 4, and no Claim 1 items (PTs assess the practice standards, drawing scenarios from across Claim 1 content domains). Per-target-set item counts are published in the blueprint tables; no percentage weighting is published.

A clinic recorded customer wait times, in minutes, for visits. The frequency table shows the results.
What is the median wait time?
Expand to wait times: . The th and th values are both , so the median is minutes.
Mia writes three survey questions:
• How many minutes do students in my class spend on homework?
• How many minutes did I spend on homework last night?
• How tall are the players on my team?
How many of the three are statistical questions?
A statistical question anticipates variability. Asking how many minutes students spend on homework, and how tall the players are, both ask about a group, so the answers can differ. Asking how many minutes I spent last night asks about one person on one night, so it has one answer. That makes statistical questions.
A student logs five daily page counts: , , , , and . A sixth day with pages read is added to the data set. How does this affect the mean?
The mean of the original five counts is pages. Because , adding pulls the mean up.
The practice times, in minutes, for five days are and What is the mean practice time?
