Tests are invaluable for teachers, school leaders, district leaders, policy-makers, the public, parents and even students -- so long as they (and the inferences mades from the data they produce) are valid.

Standardized the role of standardized testing in our schools has been on the rise for decades, and even 2015 ESSA (Every Student Succeeds Act) will do little to diminish that role. However, the tests that we use are of questionable validity. For all the criticism that psyshometricians and assessment industry professionals may make of teacher-made tests, there have long been validity problems with standardized tests which render the usefulness questionable. Historically, the assessment industry has focused on maximizing reliability, with far less attention to validity.
At AleDev, we build protocols, approaches, guides and techniques for developing standardized tests with an emphasis on validity, above all else. Primarily through our Rigorous Test Development (RTD) project, we are trying to help create better tests so that they can be useful both to those with who must take in a wide view of the progress of hundred, thousands or millions of students and are those who are focus on individual students and the content they are trying to master.
