Using a modified version of the statewide item analysis report, I examined the readiness standards that had less than 60% mastery. Each standard has both an analysis of the items themselves to infer what made them so difficult and instructional implications for educators to ensure a more successful 2026 STAAR test.
Standard | # of items | % mastery |
6.8D | 1 | 25 |
6.7D | 1 | 28 |
6.5B | 1 | 31 |
6.8A | 1 | 41 |
6.12D | 1 | 42 |
6.10A | 1 | 46 |
6.3E | 2 | 49.5 |
6.2D | 2 | 50.5 |
6.12C | 2 | 51.5 |
6.4B | 2 | 51.5 |
6.13A | 1 | 55 |
6.3D | 2 | 55 |

6.8D - 25% overall mastery
determine solutions for problems involving the area of rectangles, parallelograms, trapezoids, and triangles and volume of right rectangular prisms where dimensions are positive rational numbers
#21 - 25% correct

Analysis
Students had to apply knowledge of the area of trapezoids, rectangles, triangles, squares, and parallelograms ALL within the same problem
So many shapes sometimes leads students to attempt spatial reasoning rather calculation
Instructional Implications
Show students that the area for parallelogram, square, and rectangle are all base x height and a triangle is simple half of that
Formula for area of a trapezoid is more nuanced and students should be comfortable using formulas from the reference material
6.7D - 28% overall mastery
generate equivalent expressions using the properties of operations: inverse, identity, commutative, associative, and distributive properties
#30 - 28% correct

Analysis
Students needed knowledge of the distributive property and various ways to show division (6.2E) to solve this problem
These properties are the foundation for algebraic thinking and success in math moving forward
Instructional Implications
You cannot spend enough time with the distributive property
Use area models to graphically represent the distributive property
Start transitioning from using the ÷ symbol to fraction (/) notation to denote division

6.5B - 31% overall mastery
solve real-world problems to find the whole given a part and the percent, to find the part given the whole and the percent, and to find the percent given the part and the whole, including the use of concrete and pictorial models
#14 - 31% correct

Analysis
More students chose B (34%) than the correct answer, incorrectly dividing $36,000 by 3
Answer distribution for A (14%) and D (20%) suggest overall confusion
Instructional Implications
Emphasize that 3% increase can be calculated by multiplying by 0.03
This one-step problem could have easily been a two-step problem if students were tasked to find the new salary.
6.8A - 41% overall mastery
extend previous knowledge of triangles and their properties to include the sum of angles of a triangle, the relationship between the lengths of sides and measures of angles in a triangle, and determining when three lengths form a triangle
#31 - 31% correct

Analysis
25% chose C (three equivalent measures) and 20% chose B (angles add to 360°
Answer distribution suggests lack of familiarity with the Triangle Sum Theorem
Instructional Implications
Show the relationship between a rectangle (four right angles = 360°) and cutting it in half, creating two triangles that equal 180° each
Conceptual understanding lasts longer than memorizing random facts
6.12D - 42% overall mastery
summarize categorical data with numerical and graphical summaries, including the mode, the percent of values in each category (relative frequency table), and the percent bar graph, and use these summaries to describe the data distribution
#9 - 42% correct

Analysis
This question requires potentially 4x as much work as other problems since each answer choice must be interpreted individually
40% chose D (misinterpreted 6 a.m. as 55% rather than 45%)
Instructional Implications
Verify you are reading the percent bar graph correct by finding the value for each section and checking that the sum is 100%
Each statement should be evaluated algebraically
6.10A - 46% overall mastery
model and solve one-variable, one-step equations and inequalities that represent problems, including geometric concepts
#22 - 46% correct

Analysis
Students did not need to struggle with < or > vs ≤ or ≥
Incorrect answers ranged from 17% - 20%, signifying guessing
After identifying the unit rate, students needed to correctly interpret the inequality
Instructional Implications
Approach these problems in two steps - identifying the unit rate and interpreting the inequality
Provide students with opportunities to verbalize why they think a certain inequality is correct
6.3E - 49.5% overall mastery
multiply and divide positive rational numbers fluently
#12 - 64% correct

#20 - 35% correct

Analysis
Instructional Implications
Dividing by a fraction requires more steps than multiplying with a decimal
Cross-cancellation can make large fraction multiplication simplified
6.2D - 50.5% overall mastery
order a set of rational numbers arising from mathematical and real-world contexts
#11 - 29% full credit; 32% partial credit; 40% no credit

#33 - 56% correct

Analysis
Instructional Implications
Utilize the inequality format going in both directions
Intermix positive and negative, fractions and decimals
6.12C - 51.5% overall mastery
summarize numeric data with numerical summaries, including the mean and median (measures of center) and the range and interquartile range (IQR) (measures of spread), and use these summaries to describe the center, spread, and shape of the data distribution
#13 - 28% full credit; 29% partial credit; 43% no credit

#19- 60% correct

Analysis
Instructional Implications
When discussing numerical summaries, use language like “measures of center” and “measures of spread” to classify the different calculations
Help students understand why these measures are beneficial and what they potentially signify
6.4B - 51.5% overall mastery
apply qualitative and quantitative reasoning to solve prediction and comparison of real-world problems involving ratios and rates
#6 - 45% correct

#25 - 58% correct

Analysis
#6 asked students to use the total (20) in the proportion though it’s not given
28% chose D, multiplying 7/13 by 3000
#25 was more straightforward, offering students the opportunity to find and use a unit rate or by doubling $101.25
Reasonableness could have eliminated two answer choices (9 is slightly less than double 5, so the answer will be slightly less than double $112.50)
Instructional Implications
Instead of having students memorize one way to solve these problems, encourage and model flexible approaches to deepen understanding
6.13A - 55% overall mastery
interpret numeric data summarized in dot plots, stem-and-leaf plots, histograms, and box plots
#29 - 55% correct

Analysis
Each statement had to be evaluated separately
27% chose C (50 & 99 are both less than 200)
Instructional Implications
When evaluating statements, students should turn each sentence into an expression, equation, or inequality
6.3D - 55% overall mastery
add, subtract, multiply, and divide integers fluently
#2 - 75% correct

#24 - 35% correct

Analysis
Little difficulty with #2
#24 is closely aligned with order of operations in 5th grade (5.4F) and 6th grade (6.7A)
Answer choices (A - 25%; D - 27%) indicated large scale confusion
To get A, students multiplied -8 and 2 first
To get D, students subtracted 2 - 5, then added 3 to get 0, then added -8 and -4
Instructional Implications
Order of operations should be used fluidly with all four operations
6th graders should be including two levels of grouping and now exponents
6.6C - 58% overall mastery
represent a given situation using verbal descriptions, tables, graphs, and equations in the form y = kx or y = x + b
#8 - 43% full credit; 29% partial credit; 27% no credit

Analysis
Table of values relationship could be shown in three possible ways
y = x ÷ 4
y = x / 4
y = ¼ x
This is the first time 6.6C has asked for students to evaluate both a table of values and a graph in the same question
Instructional Implications
Tables of values, graphs, equations, and verbal descriptions should be used interchangeably to describe each other
Provide steps and tools for deciding whether it’s an additive or multiplicative relationship
