The NHS Law Signature programs consist of law 1 (street law), law 2 (criminal justice and mock trial activities), law 3 (paralegal studies, forensic psychology and mock trial activities) and speech/debate for the law student. Students participate in a regional mock trial competition and host a law week for Northside's social studies classes.

Northside is the site of the Engineering Academy, which invites students across the Lafayette area to come from their freshmen year to graduation. The Academy of Engineering has dual purposes. The main goal is to prepare students to be successful in a post-secondary field of study related to engineering or industrial technology. The second goal is to help students determine which specific engineering or industrial technology discipline most appeals to them as a possible career. Courses include engineering I and II, drafting I and II, general technology education and technology education computer applications.
