The Ages & Stages Questionnaire is a useful instrument (parent report questionnaire) which explores also other areas of development apart from communication. It is useful for children from the first months of life to 5;6 years of age. You may find information in this web page: http://www.brookespublishing.com/resource-center/screening-and-assessment/asq/
More specialized in language and communication are the MacArthur-Bates Scales (Communicative Development Inventories). They are very useful for young children. You may find more information at http://mb-cdi.stanford.edu
Another useful instrument is the Language Development Survey (http://www.ncbi.nlm.nih.gov/pubmed/2811339)

Hi, you might consider some of the work of Mark Guiberson and his colleagues on assessment tools in the speech and language domains. Also, Janitna Clifford, Janet Squires and her colleagues have done some comparative analysis on screening and evaluation tools specifically. Best, Rashida
Would it not be the case that you should be privileging IELTS and TOEFL studies in your search for the best tools? I particularly liked the TAFE system for teachers.
Hi, Miguel Pereira already mentioned the CDI. Let me just draw your attention to the short versions of these parental reports. They have been shown to be as effective, reliable and valid, and more applicable in several settings (clinical, educational, and research). Moreover, across language comparisons have revealed interesting findings. Good luck for your research.
There are several good comparison studies available in the archival journals of the American speech-Language-Hearing Association. three are attached below. Although an old articles, The McCauley and Swisher article is still useful and relevant and was a fine study. McLeod's recent study is excellent for speech screening. Hope these three help.
There is a substantial difference between Screening (Level 1 tools- glimpse to see if the child is a candidate of a full assessment which is costly in time and money) and Assessing (you have plenty evidence that the child is affected). No matter which you need to perform, there are some factors you need to examine in any tool: What is the Sensitivity of the tool: the % correct identification of those who have the disorder/delay (at least 81%)- helps decrease the number of missed cases ; Specificity the% correct identification of those who Do Not have the delay/disorder (at least 90%) to eliminate % of false postivies; Positive Probability Value (PPV): the likelihood that the person has delay/disorder; Negative Probability Value (NPV): the likelihood that the person does not have the delay/disorder; and there is the Likelihood Ratio to determine the added value to the prediction of delay/disorder presence of absence (increases correct diagnosis). There is no point purchasing or using any tool that has low or no mention of these values. I know this message will help you to choose wisely. good Luck
I am the author of a book on systems: Dynamic Systems for Everyone, Understanding How Our World Works; published by Springer.  The books deals with mechanical, human and natural systems, how they behave and interact with other system. I doubt whether that meets your needs, as you are looking into health care area. You may browse parts of the book in Amazon and decide whether that meets your needs.Â
