The Complete Guide to Standardized Tests: Everything Parents Need to Know in 2025

A standardized test is a test administered and scored in the same way for all test-takers. These tests use the same questions, time limits, and scoring procedures to ensure fair comparisons between students, schools, and districts nationwide to measure how students perform relative to the standards.

The main purpose of a standardized test in schools is to provide a uniform and consistent way to measure student achievement across different schools and districts. Districts use these results as an indicator of educational effectiveness. This allows for student performance comparisons and to identify where students may need extra support or where instruction can be improved.

Standardized tests are used to measure individual and group performance, important for schools and districts.

Achievement tests measure what students have learned in specific subjects and grade levels, testing material that has been taught throughout the school year. Examples are state tests  like STAAR (Texas), FAST (Florida), and CAASPP (California).

Among the examples are standardized tests like the Cognitive Ability Test (CogAT) used in K–12 education, the SAT and ACT used by colleges and universities to assess applicant readiness for higher education, and specialized entrance tests like the Test of Essential Academic Skills (TEAS) needed for admission into nursing programs. These tests give colleges consistent criteria to evaluate applicants and guide decisions about admissions and academic placement.

Placement tests determine the right academic levels for students, with an emphasis on the accuracy of placement to ensure students are matched with the right coursework. Examples include ALEKS for math placement and Accuplacer for college readiness. The NWEA MAP test is also commonly used by international schools as an entrance exam to assess prospective students' academic levels and ensure appropriate grade placement, particularly for students transferring from different educational systems.

Proficiency tests measure competency in specific skills, often for language learners, by assessing the depth of knowledge required for language proficiency. Examples include TOEFL, IELTS, and other language assessments.

Professional certification tests ensure competency in specific careers. Examples include USMLE for medicine, NCLEX for nursing, and the Bar Exam for law. Passing these tests can open doors to new career paths and opportunities in professional life.

Purpose: Primarily diagnostic to gauge grade-level benchmarks in basic skills. Results are tied to school accountability rather than individual promotion and shape intervention or enrichment plans.

Subjects Tested:

• Reading/Language Arts (phonics, vocabulary, comprehension)
• Mathematics (number sense, basic operations, early geometry)
• Limited Science or Social Studies in certain states

Test Format: Shorter testing windows (under two hours total) with more pictorial or read-aloud support and higher proportion of multiple-choice questions. Schools carefully schedule testing windows to minimize disruption and ensure all students are tested within the designated period.

Note: Being aware of official test dates is important for planning and preparation, as it allows educators and students to organize study schedules and ensure readiness for each assessment.

We suggest that parents and students review state-specific guidelines and practice materials to ensure the best results when preparing for various state tests.

Administered by NWEA (Northwest Evaluation Association), this computer-adaptive assessment adjusts question difficulty based on student responses. It measures growth in reading, language usage, mathematics, and science, typically administered 2-3 times per year.

Include Star Reading, Star Math, and Star Early Literacy assessments. These computer-adaptive tests provide quick screenings (15-30 minutes) to identify instructional levels and monitor progress throughout the school year.

Percentile Rank

Indicates what percentage of students scored at or below your child's score. A percentile rank of 75 means 75% of students scored the same or lower.

Standard Score

Converted scores often presented on a scale with a mean of 100, allowing easy comparisons between different tests and age groups.

Grade-Equivalent Score

Compares your child's performance against average performance of students at other grade levels, though this can sometimes be misleading.

Standardized tests offer various accommodations to ensure fair testing for students with disabilities:

Presentation Accommodations:

Braille or large print versions

Audio versions or read-aloud support

Sign language interpretation

Response Accommodations:

Use of scribe or typing instead of handwriting

Marking answers directly in test booklet

Timing and Scheduling:

Extended time (50% or 100% additional time)

Frequent breaks

Testing over multiple days

Setting Accommodations:

Wheelchair-accessible rooms

Quiet spaces with fewer distractions

Separate testing locations

The key to effective test preparation lies in using materials specifically designed for each assessment type, as different tests require distinct approaches and skill sets.

Many free standardized test practice resources are available online:

State education department websites often provide sample questions

Educational publishers frequently provide sample materials

School districts may offer practice tests through learning management systems

TestPrep-Online has a wealth of free sample tests

Educational Concerns

• Narrowing Curriculum: Schools may focus heavily on tested subjects, reducing time for art, music, or social studies
• Teaching to the Test: Emphasis on memorization rather than deep learning and critical thinking
• Limited Assessment: Scores don't capture creativity, problem-solving skills, or overall growth

Student and Family Impact

• High Pressure and Stress: Significant anxiety for students, teachers, and parents
• One-Size-Fits-All Approach: Doesn't account for individual learning styles and needs

Equity Concerns

• Fairness and Bias: Tests may favor students based on cultural background or access to resources

As education continues to evolve, standardized testing adapts to new challenges and opportunities. Computer-based testing is becoming the norm, allowing for more interactive question types and immediate scoring. However, ongoing debates about test effectiveness, equity, and student stress continue to shape testing policies and practices.

Key Message: Success comes from understanding your child's individual needs and providing balanced preparation without excessive stress.

Main Recommendations: Stay informed about testing requirements, use appropriate prep resources, and communicate openly with teachers and schools.
