Common questions
Does CS++ include a full-length NES 315 practice test?
Yes - two of them. Each is a timed mock exam built to the published 315 blueprint: 100 selected-response items and 2 hours of testing time, drawn to the official domain percentages rather than to a generic CS mix. The two forms share no questions, so a second sitting measures you again instead of re-testing what you remember. Each attempt reports an estimated scaled score against the 220 passing standard and a per-domain breakdown showing which domain to study next.
What test do I take for the Washington computer science endorsement?
Washington uses the NES Computer Science (315) test through its WEST program. If you searched for a "WEST-E Computer Science" test, this is it - the CS assessment is delivered as NES 315.
How many questions are on the NES 315?
The NES Computer Science (315) has approximately 100 multiple-choice questions with 2 hours of testing time. It is computer-based and registration costs $119.
What score do I need to pass the NES 315?
Washington and Tennessee require a score of 220. Utah also accepts the NES 315 for its computer science endorsements; each state sets its own passing score.
What is on the NES Computer Science exam?
Four domains: programming concepts (36%), computational thinking and data analysis (28%), computing systems/networks/Internet (18%), and impacts of computing and learning environments (18%).
Which states accept the NES 315?
Washington, where it is the computer science endorsement test, plus Tennessee and Utah, which accept it as an alternative to the Praxis 5652. CS++ Certification Prep covers both tests.
Do I get a certificate of completion?
Yes. Once you’ve marked every study unit for this exam complete and passed one of its full-length mock exams, you can print a CS++ certificate of completion. Each certificate has a link anyone can use to verify it. It shows preparation; it’s not a teaching credential and doesn’t carry continuing-education hours.
Can my district, ESC or prep program buy this for candidates?
Yes. Programs buy one code per candidate: $39 each, $29 each for 10–24, or $24 each for 25 or more, priced per order. Pay by card online and get the codes right away, or by purchase order; unused codes don’t expire. Buy or request a quote at csplusplus.com/teacher-certification/for-schools. Coordinators can follow each candidate’s progress. Instructors who’d rather have candidates pay for themselves can create a free group.
