Written language is a complex set of skills that facilitate communication and that are developed in a predictable sequence. It is therefore possible to analyze current skills, identify deficits, plan interventions, and determine the effectiveness of the intervention. To effectively accomplish these tasks, educators need to choose appropriate assessment tools. The authors discuss the strengths and weaknesses of informal written assessments and of standardized written assessments. A table of the better known and more frequently used standardized written language assessments is presented that includes test title, publisher, Web site URL, normative group, indication of its focus (spelling, style, or mechanics), age of normative group, and method of administration. This information will help readers in the selection of written language assessment tools. C ommunication is a critically important process among humans. According to Hardman, Drew, and Egan (2008), "Communication is the exchange of ideas, opinions, or facts between senders and receivers. It requires that a sender (an individual or group) compose or transmit a message and that a receiver decode and understand the message. The sender and receiver are therefore partners in the communication process" (p. 294). The ability to communicate efficiently is one characteristic that sets humans apart from other animal species. Indeed, without the ability to communicate effectively, individuals would have a very difficult time in social settings, work settings, and educational settings. Communication is an integral component of human existence.Communication is one part language and one part speech. However, language can exist without speech, as is the case in written language. Written language consists of several different components, including penmanship, spelling, grammar, punctuation, and conveyance of meaning with words. Although individuals can communicate using oral language, written language is critical for extended communication.For most children, basic written language skills are learned during the elementary grades. Although many children enter kindergarten with a rudimentary set of written language skills, it is during elementary school that they expand on these skills. In addition to enabling elementary-age students to communicate, the skills learned during the early grades are critical for academic success in higher grade levels and postsecondary education. Adults need written language skills not only to communicate with others but also to be successful in employment and other activities. Without the ability to express oneself through written language, individuals are at a significant disadvantage, not only in educational environments but also in many life pursuits. Adults use written language daily in such activities as making notes for themselves and communicating with others. Even with the expanded use of computers and other technologies, individuals must be able to put their thoughts and ideas into written language to communicate with others.Given the i...
