The TExES Bilingual Target Language Proficiency Test (BTLPT) - Spanish (190) will be offered for the first time in early 2009. It will be offered via computer during one week administration windows at various times throughout the year.
The Writing section of the BTLPT - Spanish requires you to enter written responses on the computer. An alternate character toolbar for inputting Spanish accents and characters is built into the test.
There is a tutorial for this toolbar that will let you practice using the toolbar before taking the test. If you are planning to take the BTLPT - Spanish, you are strongly urged to take this tutorial.
