The PSSA vs. TerraNova Philadelphia admissions question is one I hear from parents every fall — and most families don't realize there are three separate assessment paths to qualify for George Washington Carver High School of Engineering and Science. Students lose their shot at Carver not because their scores are too low, but because their family didn't know which test counted, when to submit it, or what percentile actually clears the eligibility bar. This article gives you the exact numbers and decision steps you need before the September application window opens.

What PSSA Score Does Your Child Need for Carver Engineering and Science Admissions?
Carver requires PSSA ELA and Math scores at or above the 65th percentile. Your child must score higher than 65% of Pennsylvania students in their grade on both sections — not just one.
The district uses your child's best scores from the two most recent school years. If your 7th grader scored at the 60th percentile in 6th grade but reached the 70th percentile in 7th grade, the 7th-grade score is what counts.
PSSA scores are reported in four performance levels: Below Basic, Basic, Proficient, and Advanced. Reaching the 65th percentile typically means scoring solidly in the Proficient range or at the lower end of Advanced — but the exact percentile that corresponds to each performance level shifts slightly from year to year based on that year's cut scores. Proficient does not automatically equal the 65th percentile, so check the score report's actual percentile column, not just the performance level label.
The PSSA is given each spring, typically in April. If your child attends a Philadelphia public or charter school, they take it at their school — no separate registration needed. Scores are usually available by summer, well before the fall application window.
TerraNova as an Alternative to the PSSA: Philadelphia School Selection Rules for Private and Homeschool Families
If your child attends a private school, a homeschool program, or any setting where the PSSA is not given, you are not locked out of Carver. Philadelphia's School Selection process accepts three versions of the TerraNova — TerraNova2, TerraNova3, and TerraNova NEXT — as a direct alternative to the PSSA for Philadelphia magnet school admissions.
The ERB-CTP (Educational Records Bureau Comprehensive Testing Program) is also accepted. Other approved state standardized assessments qualify as well, as long as they cover ELA and Math at the appropriate grade level.
Here is how the alternative path works in practice:
- Your child takes TerraNova or ERB-CTP through a private school, homeschool co-op, or independent testing center in the Philadelphia area.
- You receive a score report showing national percentile rankings in Reading and Math.
- You upload or submit that score report through the district's online School Selection application during the fall window (September 8 – October 23).
- The district converts your child's national percentile scores into a PSSA-equivalent percentile for eligibility screening.
Philadelphia public and charter school students may not opt out of the PSSA in favor of TerraNova when applying to criteria-based schools. The TerraNova and ERB-CTP paths exist specifically for students who are not in the district's testing system.
PSSA vs. TerraNova vs. ERB-CTP for Philadelphia Magnet School Admissions: Which Test Fits Your Child?
The right test depends mostly on where your child is schooled — but understanding how these assessments differ helps you prep more strategically regardless of which path you take.
PSSA: Criterion-Referenced Against Pennsylvania Standards
The PSSA measures how well your child meets specific Pennsylvania Core academic standards. Every question traces back to a defined PA learning standard. If your child attends a Philadelphia public or charter school, they take the PSSA automatically each spring.
PSSA prep means mastering PA Core ELA and Math content at the appropriate grade level. Constructed response and extended response questions account for a significant share of the ELA score, so written communication skills still matter — even though Carver no longer requires a separate admissions essay.
TerraNova: Norm-Referenced Against a National Peer Group
The TerraNova compares your child to a national sample of same-grade students. It focuses on reasoning, inference, and problem-solving rather than state-standard recall. A student who is a strong logical thinker but has gaps in Pennsylvania-specific curriculum content may find the TerraNova a better match.
TerraNova Reading and Math questions frequently involve data interpretation, scientific reasoning passages, and multi-step quantitative problems — the same higher-order skills that Carver's engineering curriculum demands from day one of 9th grade.
ERB-CTP: Achievement Testing Common in Independent Schools
The ERB-CTP is standard in many independent and private school settings. It provides detailed subscores in Reading Comprehension, Vocabulary, Writing Mechanics, and Mathematics. Many private-school families already have ERB-CTP scores on file, making it the easiest to submit if your child's school administers it regularly.
How the Carver Admissions Lottery Works — and Whether a Higher Test Score Helps
Once your child meets all three eligibility criteria — grades, attendance, and test scores — they enter a centralized lottery. Every eligible student enters the same pool. A score at the 98th percentile earns no better lottery position than a score at the 65th percentile.
The lottery uses the Gale-Shapley deferred acceptance algorithm — the same matching method recognized with a Nobel Prize in Economics — to assign seats based on student school rankings and available seats. You can rank up to five schools in your School Selection application.
The one structural advantage beyond meeting the cutoff is priority ZIP code status. Residents of 19121, 19132, 19133, 19135, 19136, and 19140 are drawn from a preference pool before the general applicant pool. If you live outside those ZIP codes, your child's odds depend on how many eligible students apply and how many seats remain after the priority pool is served.
Rank Carver strategically. If it is your child's top choice, rank it first. The algorithm places students at their highest-ranked school where they are eligible — but only when they rank it. A student who lists Carver second may be placed at their first-choice school instead, even if Carver had an open seat.
Carver Admissions Timeline: When Should Your Child Start Preparing?
The Carver admissions timeline runs on a two-year lead. Here is the realistic prep and application calendar for a student targeting 9th-grade enrollment in fall 2027:
- Spring 2026 (6th grade): Take PSSA — this becomes one of the two eligible score years. Begin STEM critical thinking and math reasoning practice.
- Summer 2026: Review 6th-grade PSSA results. Identify which domain — ELA or Math — needs the most work heading into 7th grade.
- Fall 2026 – Spring 2027 (7th grade): Focused prep targeting the 70th percentile or above on PSSA Math and ELA. Take PSSA in April 2027. Consider using STEM Critical Thinking Practice Tests to build the reasoning skills both the PSSA and TerraNova reward most.
- September 8, 2027: School Selection application opens. Submit best PSSA scores from 6th and 7th grade — or TerraNova / ERB-CTP scores if applicable.
- October 23, 2027: Application window closes.
- Late November 2027: Preliminary eligibility results posted.
- January–February 2028: Final eligibility and lottery results released. Offer acceptance deadline follows within days.
For TerraNova or ERB-CTP test-takers: book your spring testing appointment no later than February 2027 to make sure scores are in hand before the September application window.
Students With IEPs, 504 Plans, or EL Services: How Carver's Individualized Review Process Works
Philadelphia's School Selection process includes an Individualized Review pathway for students who receive IEP, 504, or English Learner services. Under this pathway, your child can be considered for Carver if they meet 2 of the 3 eligibility criteria rather than all three.
To access this review, indicate your child's IEP, 504, or EL status during the online School Selection application. The district does not automatically flag these students — you have to actively opt into the process.
Meeting 2 of 3 criteria does not guarantee a seat. The Individualized Review means your child's application gets a human evaluation rather than an automatic rejection. Before you apply, gather your child's IEP or 504 documentation — the review panel may request it to put attendance or test score data in context. Document your child's two strongest criteria clearly and completely in the application.
Students with IEPs have succeeded at Carver. The school's Project Lead the Way engineering program is hands-on and project-based, which works well for many learners who don't thrive in traditional lecture settings. That is exactly why the district built the Individualized Review pathway into the process.
TerraNova Prep for Philadelphia Magnet School Success: The STEM Skills That Move Scores
Carver's curriculum runs on Project Lead the Way engineering from 9th grade forward. Every course requires data analysis, logical reasoning, and applied mathematics. Those are the same skills that push PSSA Math and TerraNova Math scores above the eligibility threshold.
PSSA Math tests multi-step problem solving, algebraic reasoning, and data interpretation in real-world contexts. TerraNova Math tests the same reasoning skills against a national peer group. Neither test rewards rote memorization alone — both reward the ability to analyze information, spot patterns, and build a logical argument from evidence.
PSSA ELA constructed response questions ask your child to read a complex passage, interpret data or an argument, and write a well-reasoned response. That is critical thinking applied to reading comprehension. Students who practice structured analytical writing score higher on the constructed response section — and those skills carry straight into Carver's coursework once your child is admitted.
Strong STEM critical thinking preparation does two jobs at once: it raises your child's PSSA or TerraNova scores enough to clear the eligibility threshold, and it builds the reasoning toolkit Carver's engineering program expects from every student on the first day of 9th grade.
Frequently Asked Questions: George Washington Carver High School of Engineering and Science Admissions
Q: Can my homeschooled child use TerraNova to apply to Carver Engineering and Science?
A: Yes — Philadelphia's School Selection process accepts TerraNova2, TerraNova3, and TerraNova NEXT as direct alternatives to the PSSA. You arrange testing through a private school, homeschool co-op, or independent testing center in the Philadelphia area. Once you have scores, upload them through the district's online School Selection application during the fall window (September 8 – October 23). The district converts your child's national percentile scores into a PSSA-equivalent percentile for eligibility screening. ERB-CTP follows the same submission process. Call the Philadelphia School District's Office of Enrollment at 215-400-4000 before the application window opens to confirm the exact submission steps for your situation.
Q: Is the TerraNova harder or easier to prep for than the PSSA?
A: Neither is universally easier — they test similar skills through different lenses. The PSSA is criterion-referenced: every question ties to a specific Pennsylvania Core standard, so prep means mastering PA curriculum content. The TerraNova is norm-referenced: your child's score reflects how they compare to a national peer group, and questions lean toward reasoning and inference over state-standard recall. A strong logical thinker with gaps in Pennsylvania-specific content often scores better on TerraNova. Both tests require solid reading comprehension, mathematical reasoning, and data interpretation. Building core critical thinking and quantitative skills benefits your child on either assessment.
Q: What percentile do I need on the TerraNova to qualify for Carver?
A: Target the 80th national percentile or above on TerraNova Reading and Math. The official cutoff is the 65th percentile on PSSA-equivalent scores, but the district's TerraNova-to-PSSA conversion formula is not public. Scoring at the 80th national percentile gives your child a real buffer against any downward shift in the conversion. A score between the 65th and 79th national percentile may still convert above the cutoff — but it is not guaranteed. The 80th percentile is the safest target.
Q: Does Carver require a separate entrance exam, essay, or interview?
A: No. The Philadelphia School District eliminated the written assessment requirement for criteria-based schools beginning with the 2023-24 admissions cycle. There is no school-administered entrance exam, no interview, and no essay submission required. Eligibility is determined by three criteria only: As and Bs in four core subjects, a 95% attendance rate, and standardized test scores at or above the 65th percentile on PSSA ELA and Math — or an approved alternative. Students who meet all three enter the centralized lottery. Note that strong writing skills still matter for PSSA ELA because constructed response questions are a significant part of the ELA score.
Q: If my child attends Carver's middle school, are they guaranteed a high school seat?
A: Only if they meet all three eligibility criteria and rank Carver first on their School Selection application. Meeting two of three criteria is not enough for the guarantee. One detail many families miss: your child must still submit the School Selection application during the standard September–October window, even as a current Carver middle schooler. Missing that deadline can forfeit the guaranteed seat. Confirm your child's PSSA scores, grades, and attendance figures before assuming they qualify.
Q: Does a higher PSSA score improve my child's chances in the Carver lottery?
A: No. Once your child meets all three criteria, every eligible applicant enters the same lottery pool. A score at the 95th percentile earns no better lottery position than a score at the 65th percentile. The one factor that shifts relative odds is priority ZIP code status. Residents of 19121, 19132, 19133, 19135, 19136, and 19140 are drawn from a preference pool before the general pool fills remaining seats. Families outside those ZIP codes should rank Carver alongside four other schools to protect their overall School Selection outcome.
Q: What ZIP codes receive priority consideration, and how significant is the advantage?
A: The six priority ZIP codes for Carver are 19121, 19132, 19133, 19135, 19136, and 19140. Eligible students from these neighborhoods are drawn from a separate preference pool before remaining seats go to the general lottery pool. The district does not publish the exact number of seats held for priority applicants, so the size of the advantage shifts year to year based on applicant volume. Families outside these ZIP codes should treat Carver as a strong but competitive option and use all five school ranking slots in their application.
Q: My child has an IEP or 504 plan and doesn't meet all three criteria — can they still be considered?
A: Yes. The Individualized Review process allows students with IEP, 504, or English Learner services to be considered for Carver if they meet 2 of the 3 eligibility criteria. You must actively indicate your child's status during the online application — the district does not flag these students automatically. Before applying, gather your child's IEP or 504 documentation, because the review panel may request it to put attendance or test score data in context. The review does not guarantee admission, but it ensures your child's full record gets a human evaluation rather than an automatic rejection.
