Depiction in the series
In the season eight premiere School Daze - Part 1 and Part 2, Smolder enrolls in Twilight Sparkle's School of Friendship as a student, having been brought to Ponyville by Ember to represent the dragons. Initially, Smolder is bitter about being enrolled at the school against her will, and her attitude is made worse when Twilight's strict adherence to the Equestria Education Association's guidelines causes the school courses to be dull and boring. She also only gets along with Gallus at first due to their similar personalities.
When Smolder later cuts class with Gallus, Sandbar, Yona, Ocellus, and Silverstream, the six hang out together and end up becoming good friends. When they return to school for Friends and Family Day, they accidentally ruin the event and cause damage to the school. Chancellor Neighsay of the EEA perceives their fun and games as an attack orchestrated by non-pony creatures, and the offended tribe leaders pull their representative students out of school, including Smolder.
Not wanting to say goodbye to each other after the school is closed, Smolder and her friends go into hiding at the Castle of the Two Sisters. Though the six have fun together at first, they soon come under attack by ferocious puckwudgies, and the Mane Six save them. When Smolder and her friends are asked to come back to school, they are reluctant to continue their boring lessons, but Twilight and the others assure them things will be better and more fun than before. After Twilight defies the authority of Chancellor Neighsay and reopens the School of Friendship, Ember allows Smolder to stay.
In Grannies Gone Wild, Smolder, Yona, and Sandbar reluctantly listen to Rainbow Dash gush about the Wild Blue Yonder rollercoaster in Las Pegasus. In Horse Play, she takes part in Twilight's play about Princess Celestia.
In Non-Compete Clause, Smolder and her fellow students are taken on a teamwork field trip by Applejack and Rainbow Dash. The teachers spend most of the trip arguing amongst themselves, confusing some of the students and annoying the others (such as Smolder). When this behavior leads to Applejack and Rainbow Dash becoming trapped over a ravine, Smolder and her friends work together to rescue them. After returning to the school, Smolder and the other students tell Twilight that Applejack and Rainbow Dash's arguing taught them how not to work together, believing it was all part of the field trip.
In Molt Down, Smolder informs Spike all about the effects of the "molt". She also mentions a brother her family kicked out of their home after he went through the molt.
In Marks for Effort, Smolder appears in Applejack's class playing buckball with her fellow students and later leaving the school with her friends after a test.
In A Matter of Principals, Smolder and her classmates are shown various magical artifacts by Twilight, just before she is summoned by the Cutie Map. When Discord appoints a Dragon Sneeze tree as a substitute teacher, Smolder starts sneezing uncontrollably, spraying fire everywhere. She and her friends are later forced to run laps by Discord, who conjures up a bugbear to chase them. During the "spell-venger hunt", Smolder is paired up with Ocellus, and together they find one of the artifacts. However, both are then chased by a suit of armor that was animated by Discord. She and her friends are present when Starlight Glimmer apologizes to Discord for not including him, and offers him the job of "vice headmare".
In The Hearth's Warming Club, Smolder shows little enthusiasm for the holiday. After a prank ruins the Hearth's Warming tree, the students are all under suspicion for it, and charged with cleaning up the mess while they are questioned one by one. Smolder insists that she is innocent, and when asked about dragon traditions, she tells her friends about the Feast of Fire, where dragons tell each other stories in hopes of winning a big pile of gems. When the guilty party doesn't come forward, Smolder is accused of being the culprit by Sandbar, who believes she is acting too calm over it. When Gallus confesses that he was the culprit, resulting in him having to stay for friendship lessons over the holidays, Smolder (reluctantly, at first) joins their friends in choosing to stay with him.
In Friendship University, when Smolder and her classmates hear about Flim and Flam's Friendship University, she points out that it is a university, not just a school. In The End in Friend, Smolder and her classmates observe Rainbow Dash and Rarity as part of Twilight's lesson on compromising in friendship. In A Rockhoof and a Hard Place, Smolder is among the students who attend Rockhoof's class and become interested in his stories. She later becomes upset when he disrupts a fire-breathing contest between her and Spike.
In What Lies Beneath, Smolder and her friends start to question whether friendship is in their nature due to comments made by Cozy Glow. They later discover a mysterious cavern beneath the school and encounter a manifestation of the Tree of Harmony. To test their friendship, each student is forced to confront their worst fears, with Smolder's being admitting that she likes cute things. She later helps Ocellus overcome her own fears, and the two reunite with the rest of their friends.
In Father Knows Beast, Smolder helps Spike as he is learning to fly, and is later surprised when he gives her a pillow as a thank-you gift. After Sludge crash-lands in Ponyville, she helps bring him to Twilight's castle to recuperate. After finding Spike sleeping outside at Sludge's urging, she realizes that Sludge is manipulating him. She later helps Spike to get Sludge out of the castle, and expresses sympathy for him after Sludge admits he is not really Spike's father.
In the season eight finale School Raze, Smolder and her friends go on a field trip to Cloudsdale just before a crisis in Equestria causes magic to start disappearing. After Twilight and her friends leave for Tartarus to investigate, Smolder grows suspicious of Cozy Glow when she claims that Starlight (whom Twilight had made headmare in her absence) suddenly left, leaving Cozy in charge. She and her friends discover Chancellor Neighsay taking over the school, and Neighsay captures them under suspicion of stealing Equestria's magic themselves.
After Sandbar and the Cutie Mark Crusaders help them escape and reveal Cozy Glow's true sinister nature, they try to free a magically-trapped Starlight Glimmer, but Cozy catches them and convinces the students to turn on them. Smolder and the others get trapped with Starlight and are nearly sucked into another realm with all of Equestria's magic, but they are saved by the Tree of Harmony, and they succeed in foiling Cozy Glow's plans.

After getting permission from their kingdoms to return to Ponyville early, the Young Six each work on their own individual ways of honoring the tree's memory, with Smolder carving a memorial statue for it out of rock. In the end, they agree to form a clubhouse out of the tree's remains.

Later, Smolder listens to Garble recite poetry, and Fluttershy finds them, leading to Smolder finding out what her brother's been doing, and she agrees with Fluttershy when she points out that Spike has the strength to be himself, unlike Garble.
