Should I make an ultimatum?

I made another post in r/needadvice about my families situation that I deleted. Now I need some more advice. In a nutshell , My Mom who passed away this month was "homeschooling" my siblings and I since I was starting first grade. My dad and Mom decided she would handle all our education. Over the years she did try and bought appropriate ciriculim, but it started severely dwindling and my two youngest minor siblings barely have a first grade education.

I myself was tested at eighteen and have third year college level reading and spelling..... I'd rather not say my other levels :-[ my other three siblings are adult aged and are going to have to care for themselves. The oldest sibling has had successful career and is starting a family :-) My problem is the two minors. Putting it simply my dad is completely neglectful to them and always has been.

Forget about school, he ignores their basic everyday needs. Hygiene , nutrition , medical, dental etc... I'm making a plan to get my licence, a job and my own place. I will be two States away and his job means he is offshore one to four weeks at a time. The two adult Siblings who live at home do not drive. He has asked me to homeschool them and I refused. He refuses to put them in school because "their so behind they'll take them away" if push comes to shove he will do absolutely nothing about their education. He takes absolutely no responsibility for his family or home. The two youngest have been known not to leave the house for months at a time :-\

Should I give him an ultimatum to get them a plan for their education or I contact authorities? Should I just keep tabs for the next year and secretly/anonymously contact CPS if there's no change?

I'm definitely sticking with my plan but I'm worried about their welfare. I helped my mother raise them and I know how much of a Narcissist/psycho my dad can be.

To give you an idea of what were dealing with, :He will drive to the store usually having someone else run in for the items,: He works offshore although it has been awhile ( he asks family/coworkers for "loans") : He is severely entitled , expects everyone else to handle his business. : Doesn't follow through with promises or plans. : He sits in the living room all day on his phone, watching TV and movies expecting myself and his other children to take of him and all the housework, cooking, laundry etc

Any advice is appreciated. I don't want my siblings put in foster care but he needs a wake up call. On the other hand I believe him to be a legit Narcissist \ psychopath and manipulator who just doesn't care. :-\
