We know that Anakin is a padawan in ATOC and we know that he is a Jedi knight in ROTS.
The Clone Wars aims to fill in the details of the events between films by telling stories about the Clone Wars. It actually seems ridiculous (to me, anyway) to deliberately omit what could be argued as the single most important event to occur between films!
Was it easy for Anakin to pass the trials? How many trials did he have, and for how long? What was Obi-Wan's involvement? Did it occur closer to AOTC or ROTS? What did Anakin/Obi-Wan discuss before/after the trails, the ceremony? How did Padme support Anakin through this, if at all? What about when Anakin tells Padme of his success? What entails the actual ceremony (if any) to jedi status?
Seems like these things could be flashbacked into nearly any story that centers on Anakin.
