World famous boy wizard Harry Potter learned a thing or two throughout his not-quite-seven years studying at Hogwarts School of Witchcraft and Wizardry. Some of the professors he encountered taught him invaluable lessons in magic and morality. Others? Not so much.
Here are all of Potter's most prominent professors, from the very worst to the very best that Hogwarts ever offered:
Barty Crouch JuniorWarner Bros.
Mad-Eye who? Alastor Moody was invited to teach at Hogwarts, but before he could begin his tenure as the new Defense Against the Dark Arts professor, he was kidnapped by this tongue-flickering Death Eater. Therefore, not only is Barty a horrible person and established criminal, he's also wholly unqualified for his position. Bottom of the barrel, as it were.
Dolores UmbridgeWarner Bros.
Pretty psychotic in pink, this Ministry of Magic transplant and He-Who-Shall-Not-Be-Named loyalist went so far as to physically abuse her students, all while serving the Dark Lord. Worst. Headmistress. Ever.
Quirinus QuirrellWarner Bros.
You kind of have to feel bad for the guy. The purple turban-wearing Ravenclaw only wanted to bolster his reputation and magical knowhow by seeking out Voldemort and bringing new information to the wizarding world. Unfortunately, his body wound up in Voldemort's possession, making him a rather crummy teacher during the last year of his life.
Gilderoy LockhartWarner Bros.
If this was a list of "most arrogant Hogwarts professors," this misguided hot-shot would have first place on lock. As it is, he's one of the worst Hogwarts professors we've ever seen, utterly disastrous with a wand, and a complete coward to the core. More harmless than others, more harmful than most.
Horace SlughornWarner Bros.
Like Lockhart, he's more harmless than harmful — except for that whole teaching Tom Riddle about Horcruxes thing. Not so great. Also not great that he plays favorites, but he's hardly unique in that regard as far as the Hogwarts faculty goes.
Rubeus HagridWarner Bros.
He's a great friend, a great mentor, and even a great teacher. But as far as an employable teacher? Maybe not so much. He's too emotional, too easily embarrassed, lacks confidence… Hagrid makes himself an easy target for students to pick on. Best to stick to keeping the keys and grounds, big guy.
Sybill TrelawneyWarner Bros.
What she lacks in social skills, Trelawney makes up for in divination skills. Sure, she's not always on point, but she did accurately make the prophecy about Voldemort's defeat at the hands of Harry Potter. Professor Trelawney also scores points for longevity, holding the position of Professor of Divination ever since 1979. Pretty strong run.
Severus SnapeWarner Bros.
Snape boasted an impressive tenure at Hogwarts, running Potions throughout the 1980s and much of the 90s. He knew his way around the classroom, was firm with his students, and despite appearances to the contrary he did everything he possibly could to protect Harry and remain loyal to Dumbledore's cause. All good things. That said, no amount of secret noble causes can erase one simple fact: Severus Snape is a jerk. (And he killed Dumbledore.)
Remus LupinWarner Bros.
Aside from Snape and Dumbledore, no other Hogwarts professor shared more of a personal connection with Harry than Remus, one of James Potter's oldest and closest friends. He was a phenomenal wizard and patient instructor, giving Harry the tools he needed to confront his fears and, eventually, destroy Voldemort. That said, Lupin's one-year stint at Hogwarts is too brief to move him further up the list; plus, that whole werewolf thing is kind of a safety hazard for students.
Pomona SproutWarner Bros.
One of the longest tenured Hogwarts professors during Harry's time at the school, Professor Sprout has been at the helm of the Herbology department for decades. While Harry never totally clicked with that brand of magic, Sprout nursed such an interest in the art in Neville Longbottom that he went on to become Head of Herbology by 2014.
Filius FlitwickWarner Bros.
Ravenclaw's Head of House, and Hogwarts' premiere Charms master, is sometimes seen as a practical joke, especially when placed next to the staggeringly sized Hagrid. But he's got a good heart, too, and on top of that, was once crowned the Dueling Champion, proving his prowess with a wand and on the battlefield during the Battle of Hogwarts. Best part of all? He's the king of the Frog Choir.
Albus DumbledoreWarner Bros.
What's there to say? The Hogwarts headmaster's legendary resumé speaks for itself. Few others imparted such wisdom and love on Harry throughout his time at the school, to the point where some very rightfully accused Albus of favoritism. That's a strike against Dumbledore, perhaps, but his brilliant intellect, his remarkable skills as a wizard, and his endless compassion keep him right at the top of the list — with only one professor ahead of him.
Minerva McGonagallWarner Bros.
She wasn't Harry's favorite professor, and Harry wasn't her favorite student — and that's the point. Professor McGonagall, one of few animagus, rarely plays favorites, treats all who deserve it with respect and equality, compassionate but with a firm hand. She's not the most obvious of Potter's mentors, but what she lacked in persistent one-on-one face time, she made up for in leading by example. There's no better choice to succeed Albus Dumbledore — as the Dowager Countess of Hogwarts, as it were.
