What are good successive assignments for squad leaders, besides other leadership positions?

Company Operations Sergeant
Supervisory Training NCO
Broadening Assignments such as Drill Sergeant, Recruiter, Small Group Instructor
Any staff positions (relevant to MOS and unit requirements) at BN or BDE-level

Good question, sir. A lot of raters and S/Rs are struggling with this section of the 2166-9

1SG Healy, thank you, those are good and I will use one or two this rating period!
Chief Baker, specifically for Engineers.

I have a SL that who I am not comfortable with being a platoon sergeant. He is a great 12R (electrician) and he does this Civillian side (This is from the National Guard perspective) but his leadership skills are greatly lacking. Commonly my PSG has to bypass him and get information from his E-5's as well as rely on them to delegate. If this sounds odd, I assure you it is not uncommon in the reserve components at least from my experience (which, seeing as I am a Lieutenant citing my 'experience' can be taken with as much salt as you desire). But none the less its extremely frustrating.

I have seen HAZMAT and EO NCO's get lucrative offers to work in Corporate America.
