Educational stage in the context of International Standard Classification of Education

Spanish is the second most spoken language in the United States, after English. Approximately 45 million people aged five or older speak Spanish at home, representing about 14% of the U.S. population. Broader estimates place the total number of Spanish speakers—including native speakers, heritage speakers, and second-language speakers—at around 59 million, or roughly 18% of the population. The North American Academy of the Spanish Language (Academia Norteamericana de la Lengua Española) serves as the official institution dedicated to the promotion and regulation of the Spanish language in the United States.

In the United States, the number of Hispanophones exceeds the combined total of speakers of French, German, Italian, Portuguese, Hawaiian, the Indo-Aryan languages, the various varieties of Chinese, Arabic and the Native American languages. The U.S. also has the second largest Spanish-speaking population in the world, after Mexico. According to the 2024 American Community Survey conducted by the U.S. Census Bureau, 44.9 million people aged five or older speak Spanish at home — more than twice as many as in 1990. Spanish is also the most studied language in the United States after English, with approximately 8 million students enrolled in Spanish courses at various educational levels. The use and importance of Spanish in the United States has increased significantly as Hispanics are one of the fastest growing ethnic groups in the country. While the proportion of Hispanics who use Spanish in major urban areas has declined, the absolute number of Spanish speakers nationwide, as well as the use of Spanish at home, continues to grow annually.

Third grade (also 3rd Grade or Grade 3) is the third year of formal or compulsory education. It is the third year of primary school. Children in third grade are usually 8–9 years old.

Middle school, also known as intermediate school, junior high school, junior secondary school, or lower secondary school, is an educational stage between primary school and secondary school.

Twelfth Grade (also known as Grade 12, Senior Year, Standard 12, 12th Standard, 12th Class, or Class 12th or Class 12) is the name in many parts of the world for the twelfth and final year of formal or compulsory education, typically the final year of secondary school and K–12. Students in twelfth grade are usually 17-18 years old. Some countries have a thirteenth grade, while other countries do not have a 12th grade/year at all.

The Common Core State Standards Initiative, also known as simply Common Core, is an American, multi-state educational initiative which began in 2010 with the goal of increasing consistency across state standards, or what K–12 students throughout the United States should know in English language arts and mathematics at the conclusion of each school grade. The initiative was sponsored by the National Governors Association and the Council of Chief State School Officers.

The initiative also sought to provide states and schools with articulated expectations around the skills students graduating from high school needed in order to be prepared to enter credit-bearing courses at two- or four-year college programs or to enter the workforce.

A form is an educational stage, class, or grouping of pupils in a school. The term is used predominantly in the United Kingdom, although some schools, mostly private, in other countries also use the title. Pupils are usually grouped in forms according to age and will remain with the same group for a number of years, or sometimes their entire school career.

Seventh grade (also 7th Grade or Grade 7) is the seventh year of formal or compulsory education in the USA. The seventh grade is typically the first or second year of middle school. In the United States, kids in seventh grade are usually around 12–13 years old. It is the eighth school year since kindergarten. Different terms and numbers are used in other parts of the world.

Eighth grade (also 8th Grade or Grade 8) is the eighth year of formal or compulsory education in the United States. The eighth grade is the second, third, or fourth (and typically final) year of middle school. Students in eighth grade are usually 13–14 years old. Different terms and numbers are used in other parts of the world.

A word list is a list of words in a lexicon, generally sorted by frequency of occurrence (either by graded levels, or as a ranked list). A word list is compiled by lexical frequency analysis within a given text corpus, and is used in corpus linguistics to investigate genealogies and evolution of languages and texts. A word which appears only once in the corpus is called a hapax legomena. In pedagogy, word lists are used in curriculum design for vocabulary acquisition. A lexicon sorted by frequency "provides a rational basis for making sure that learners get the best return for their vocabulary learning effort" (Nation 1997), but is mainly intended for course writers, not directly for learners. Frequency lists are also made for lexicographical purposes, serving as a sort of checklist to ensure that common words are not left out. Some major pitfalls are the corpus content, the corpus register, and the definition of "word". While word counting is a thousand years old, with still gigantic analysis done by hand in the mid-20th century, natural language electronic processing of large corpora such as movie subtitles (SUBTLEX megastudy) has accelerated the research field.

In computational linguistics, a frequency list is a sorted list of words (word types) together with their frequency, where frequency here usually means the number of occurrences in a given corpus, from which the rank can be derived as the position in the list.
