If you have been confused by the pile of test names your child brings home, you are not imagining it. New Mexico does not run one simple statewide test. It runs a stack: the NM-MSSA for reading and math in grades 3 through 8, the NM-ASR for science in grades 5, 8, and 11, and SAT School Day for eleventh graders. This system is the state’s post-PARCC compromise. New Mexico left the PARCC consortium and built a Cognia-developed test for the younger grades, added a phenomenon-based science test delivered through the University of Kansas Kite platform, and adopted the SAT as its high school accountability measure. Knowing which test applies to your child’s grade is the first thing worth sorting out.
What MSSA Looks Like: Format and Item Types
The NM-MSSA (New Mexico Measures of Student Success and Achievement) is built by Cognia and delivered on a computer through the iTester platform, with paper versions available for students who need them. The test is untimed, but it is scheduled around two sessions in each subject: two math sessions and two reading sessions that run roughly 60 to 90 minutes each. Most questions are machine-scored items worth one or two points, and every subject also includes a hand-scored piece: math adds a longer constructed-response item worth three points, and reading adds a writing prompt worth up to seven points where your child plans and writes an extended response.
The science test, the NM-ASR (New Mexico Assessment of Science Readiness), has its own shape. It runs in three sessions totaling about 150 minutes in grades 5 and 8 and about 165 minutes in grade 11. Rather than isolated questions, it leans on stimulus-based blocks: a science scenario or data set followed by a cluster of machine-scored questions, plus stand-alone questions and open-ended items that a human scores. Its machine-scored questions come in point-and-click formats such as drop-down, hot spot, matching, and ordering. In grade 11, reading, writing, and math are measured instead by SAT School Day, which follows the College Board’s SAT format and reports section scores from 200 to 800.
The alphabet soup, sorted by grade
Here is the plain-English map. In grades 3, 4, 6, and 7, your child takes the NM-MSSA in language arts and mathematics, and nothing else at the state summative level. In grades 5 and 8, your child takes the NM-MSSA plus the NM-ASR science test. In grade 11, the mix changes entirely: SAT School Day stands in for the reading, writing, and math test, and the NM-ASR science test appears one final time. English learners take ACCESS for ELLs every year on top of these, and a small number of students with the most significant cognitive disabilities take Dynamic Learning Maps instead of the general tests.
Testing in Spanish is a real pathway, not a footnote
New Mexico is one of the few states where Spanish-language assessment is a genuine, built-in option rather than a translation afterthought. Qualifying English learners can take Spanish-language versions of the NM-MSSA language arts and math tests, the science test offers English and Spanish glossaries, and high school English learners may take a Spanish Reading or Spanish Language Arts assessment in place of the SAT reading and writing portion. This reflects New Mexico’s bilingual education history and its large population of Spanish-speaking families. One caution worth stating plainly: eligibility for the Spanish pathway is not simply parent preference. It depends on your child’s English learner status and the language decisions your school and district make under state rules. If a Spanish-language option matters to your family, ask your child’s teacher or the school testing coordinator how eligibility is determined at your school.
How the science test is different
The NM-ASR is not a fact-recall quiz. It is built around science phenomena: your child works from a real scenario or data set and reasons through it rather than reciting memorized facts. It measures New Mexico STEM Ready! Science Standards, which combine the Next Generation Science Standards with six New Mexico-specific standards. Grade 11 students get a periodic table, and a science glossary is available in English and Spanish. If your fifth or eighth grader says the science test asked them to explain their thinking rather than bubble in a single answer, that is the design working as intended.
What the score levels mean
Both the NM-MSSA and the NM-ASR report four performance levels: Novice, Nearing Proficiency, Proficient, and Advanced. Proficient and Advanced signal that a student has met grade-level expectations. Each report also comes with a scale score and a confidence band, which shows the range of scores your child might earn on a different day, a reminder that a single number is an estimate, not a verdict. The scale scores are grade-numbered in a way that is oddly helpful once you see the pattern: grade 3 scores sit in the 300s, grade 5 in the 500s, grade 8 in the 800s. Reading reports also include a Lexile measure and math reports a Quantile measure, both of which help you find books and materials at your child’s level.
Can you opt out?
This is where you should be cautious, and where district guidance matters most. New Mexico does not appear to offer a general parent opt-out right for statewide assessments the way some states do. The testing manuals treat participation as the default and list only specific exceptions, such as an approved medical exemption or a first-year English learner’s exemption from the language arts portion. Parents sometimes discuss “refusal,” but that is not the same thing as an officially excused opt-out, and it can affect a school’s participation rate. New Mexico has used a participation threshold in its accountability math: currently, schools that fall below 95 percent participation can see eligible-but-not-tested students counted in the proficiency calculation, which pulls the school’s numbers down. Because the exact consequences here are unsettled and local practice varies, ask your district’s testing coordinator before making any decision.
What scores decide, and what they don’t
For grades 3 through 8, state sources describe the NM-MSSA as one measure of progress, not an automatic promotion or retention test. It is primarily an accountability and progress signal, though a district may look at assessment data as one piece of a broader academic picture. Promotion and grading decisions live with your local district, so check its policy rather than assuming the state test controls them. At the high school level, graduation rules are broader than any single score: the state does not require a specific SAT School Day or science cut score to graduate, though local boards can set additional requirements. The honest summary is that these tests feed school accountability and public reporting far more than they decide any one child’s path.
