What are the NES exams?

You have almost completed your teacher education journey. The final hurdle is the NES examination to become certified. What are the NES exams?

What is the National Evaluation Series (NES)?

The National Evaluation Series (NES) teacher certification tests are delivered through Pearson’s network of computer-based test (CBT) centers. Aligned to national subject and pedagogy standards, these standards-based tests are taken by individuals pursuing certification as entry-level teachers. NES test scores are currently acceptable for certification in Arizona, California, Illinois, New Mexico, Oregon, Washington, and Wisconsin. NES provides for interstate portability of test results and simplifies candidate comparisons between states.

NES offers exams ranging from Essential Academic Skills (Reading, Writing, Mathematics, and Social Sciences) to Professional Knowledge at both the elementary and secondary levels, Elementary and Early Childhood, Middle School and Secondary level specialty areas, and K-12 areas of specialization. Exams required for certification vary from state to state. The NES website can be helpful in determining which tests best meet your needs for certification.

The format for most of the NES exams is multiple-choice with the results provided at the testing site upon the completion of the test. Some tests may include constructed response items. The results of these are available within four weeks of the exams. Scores are scaled from 100 to 300 with 220 being the national benchmark, although the state benchmarks may differ. The length of each exam fluctuates according to the individual test. These time allowances are available at the NES website.

NES Chemistry - FAQ Sample Questions

What are acids according to the Bronsted Lowry theory?

Correct Answer:

none of the listed answers
according to the bronsted-lowry theory, which was independently proposed by johannes nicolaus brønsted and thomas martin lowry in 1923, acids and bases are defined by the way they react with each other. specifically, this theory expanded the definition of acids and bases beyond their behavior in water alone, which was a limitation of the earlier arrhenius definition.

in the bronsted-lowry framework, an acid is defined as a substance that can donate a proton (a hydrogen ion, h+) to another substance. this is a significant departure from the arrhenius definition, which characterizes acids as compounds that increase the concentration of hydrogen ions (h+) in water. the bronsted-lowry definition is more general and can be applied to reactions that do not involve water. for instance, the reaction between ammonia (nh3) and hydrogen chloride (hcl) gas, where nh3 acts as a base and hcl as an acid, can be explained using this theory even though no water is involved.

a key aspect of the bronsted-lowry theory is that it introduces the concept of conjugate acid-base pairs. when an acid donates a proton, it forms a conjugate base, which is the species that remains after the proton is lost. similarly, when a base accepts a proton, it forms a conjugate acid. this concept helps in understanding the reversible nature of acid-base reactions and allows for a broader application in different chemical contexts.

it's important to clarify what bronsted-lowry acids are not, as per your query's multiple-choice format. they are not defined as "proton acceptors" — that description fits bronsted-lowry bases. additionally, they are not defined merely as "electron pair acceptors" — this is a characteristic generally used in the lewis theory of acids and bases, where an acid is considered as an electron pair acceptor. furthermore, bronsted-lowry acids are not substances that directly produce hydroxide ions (oh-) in solution; this again aligns more closely with the arrhenius definition of bases, which increase the concentration of hydroxide ions in water.

therefore, in the context of the bronsted-lowry theory, the correct answer to the question regarding the nature of acids is that they are "proton donors." this definition succinctly captures the essence of what acids do in the vast majority of chemical reactions where they participate, according to this theory. the other options listed (proton acceptors, electron pair acceptors, and substances that produce hydroxide ions) do not accurately describe acids under the bronsted-lowry theory and hence are correctly labeled as "none of the listed answers."
