Automated Assessment Tools (AATs) have been used in undergraduate CS education for decades, including a handful of widely used tools and a plethora of home-grown, in-house systems at many universities. TA-Bot, a modular AAT, has existed in some form for 25 years serving thousands of students across multiple universities. Recent work has gone into making TA-Bot more beginner-friendly for CS1 students. Previous research has shown that the earlier students start assignments, the better scores they receive. TA-Bot implements a novel dynamic rate limiting system to incentivize earlier student submissions. The experiment discussed used TA-Bot over three semesters involving 145 students in CS1. When the dynamic rate limiting was enabled, students tended to start assignments earlier.
