10Need Test Blueprint Assure that what should be taught is tested. Assure a balanced coverage of Performance Objectives.
11Test Blueprint Define what tests will cover. Guide for reporting. Keep test forms parallel.Pre/post tests
12What will be reported? Strands Concepts Performance Objectives Vocabulary5 items for percent correct score10 items for scaled scoresStandards or outcomes All this based on math and reading. Highly suspect in survey tests like science and social studies.
13One Type of Blueprint TEKS Number Knowledge Items Application Items 1.2152.738etc.
14What makes some test items better than others? There is no such thing as a perfect item.
15Thought Provoking Test Items Require the use of both knowledge and skills.May cover more than one TEKS.Go beyond reading and recalling.Have to choose the best fit TEKS

Which of these models shows the orbit of the Earth?Since we do not know if the item is focusing on the shape of the orbit or exaggeration of the orbit a knowledgeable student will not know which to answer. Except that the only correct answer shows the planet tilt. Which was not what the question was about
55Factual information should be accurate and logical. Onion root do not generally grow to a length of 300 centimeters and even if they did they would not grow as fast as indicated by the graph.
