The Language Use Inventory (LUI) is only to be administered, scored, and interpreted by speech-language pathologists, educational diagnosticians, psychologists, clinicians, health professionals, early interventionists and other professionals who have training or experience in administering, scoring, and interpreting the results of standardized tests. In particular, users of the LUI should have a general knowledge of measurement principles and of the limitations of test interpretation as called for in such policy statements as the Standards for Educational and Psychological Testing (AERA, APA, & NCME, 1999) and the Report of the Task Force on Test User Qualifications (APA, 2000). For these users, a review of this manual, combined with practice administering, scoring, and interpreting the scores, is sufficient for learning how to use the LUI.
Students enrolled in graduate programs may also purchase the LUI for research purposes if the purchase order is countersigned by the student’s research advisor or department head.
It is not the responsibility of Knowledge in Development to ensure that tests are used properly once they leave the firm; that responsibility remains solely with the test purchaser, even in cases where the purchaser delegates the administration and/or interpretation of the LUI to someone else.
By purchasing the Language Use Inventory and associated materials, you are acknowledging agreement with the guidelines on user qualifications described above; your purchase also implies agreement with the terms and conditions laid out below.
Terms and Conditions
Acceptance of Terms and Conditions
Sales of test instruments, related materials, and services are based upon acceptance of the various terms and conditions and adherence to all policies described in this agreement. Purchasers agree to be bound to all terms and conditions by placing an order for materials, or by part or total payment of Knowledge in Development‘s invoice for any tests, materials, or services ordered. No modification or additions to these terms and conditions are binding upon Knowledge in Development unless previously agreed to in writing by an authorized representative of Knowledge in Development.
Terms and Conditions of Purchase
1. Limited Warranty. Knowledge in Development warrants that its products meet applicable professional standards and will be manufactured in usable quality. Knowledge in Development makes no other warranties, expressed or implied, including warranties of merchantability or fitness for a particular purpose. Replacement of materials, or refund of all or a portion of the purchase price (based upon the salable condition of the materials), at Knowledge in Development’s sole option and in accordance with the product return policy constitutes the purchaser’s sole and exclusive remedy, in lieu of all remedies and actual, consequential, special, incidental, or other damages in connection with the product and any use or misuse thereof. Knowledge in Development will not, under any circumstances, be liable for purchaser’s expense for delays, for costs of substitute materials, or for possible lost income, grants, profits, or any other special or consequential damages that may result from using a product. Some jurisdictions restrict certain limitation of warranties, so some or all of the above limitations may not apply to you.
2. Confidentiality. Purchaser acknowledges and agrees the contents of Knowledge in Development’s tests include confidential and proprietary material, information, and procedures. Purchaser will not resell or otherwise distribute materials, or authorize or allow disclosure of the contents of a test instrument protocol, including test questions and answers, or normative data, except under the limited circumstances described in the section titled “Maintenance of Test Security,” or as otherwise contemplated in the manual associated with the test.
3. Maintenance of Test Security. Users of the LUI are responsible for ensuring that all materials related to the LUI (the Language Use Inventory, the LUI Score Sheet, and the Manual) remain secure. To administer the LUI, it must be shared with the child’s parent(s). Parents are permitted to make a single copy of the completed inventory for their own personal archival records, but are not permitted to copy or distribute the uncompleted or completed LUI for any other purpose. A single copy of the completed LUI Score Sheet (i.e., raw scores and percentile equivalents) can also be given to parents for their child’s health record. Users are not permitted to copy or disclose any materials related to the LUI, except to a parent for the purpose of having the parent complete the inventory or to appropriate personnel involved in the scoring and interpretation of a child’s score. Under no circumstances should LUI materials be resold or displayed in locations where unqualified individuals can purchase or view partial or complete portions of the inventory or the manual (this includes all websites) as doing so could compromise the validity of the LUI’s results as well as the LUI’s value as a measurement tool.

5. Limitation of Liability. IN NO EVENT WILL KNOWLEDGE IN DEVELOPMENT BE LIABLE FOR DAMAGES ARISING UNDER THIS AGREEMENT, OR OTHERWISE ARISING FROM THE ORDER(S) CONTEMPLATED UNDER THIS AGREEMENT, IN EXCESS OF THE AMOUNTS PAID FOR THE PRODUCT(S) WHICH DIRECTLY CAUSED THE DAMAGE.
6. Notices. Any required notices shall be given in writing to the Purchaser at the most recent contact information provided by Purchaser to Knowledge in Development. We may send you notice by electronic mail as an alternative to conventional mail.
