A Chester County teacher has pleaded guilty to charges stemming from a sexual relationship with a teen student and allegations that she provided the student with marijuana, according to the District Attorney’s Office.

Michelle Mercogliano, 35, of Phoenixville, was accused of beginning a sexual relationship with a 16-year-old student that started in February 2025. Prosecutors also alleged that she gave the teenager marijuana at least 15 times.

The criminal complaint states that Mercogliano used her cell phone to text the minor and relied on the social media platform Snapchat to avoid detection.

On May 1, 2026, Mercogliano entered a guilty plea to charges including institutional sexual assault and corruption of minors.

Sentence Includes Prison Time and Long-Term Supervision

Mercogliano was sentenced to 15 months in a Chester County prison. After her release, she will be supervised by a probation officer for at least 80 months.

At the time of her arrest, Mercogliano worked as a special education teacher at Conestoga High School. Since then, she has forfeited her teaching license. While on probation, she will not be allowed to work with children.

Prior Employment Listed in Officials’ Records

Legal Options for Victims of Teacher Sexual Abuse

Pennsylvania sexual abuse cases involving teachers can be especially complex for survivors, who may be navigating trauma, school-related retaliation concerns, and questions about timing and evidence. We spoke with experienced sexual abuse lawyer Ashley DiLiberto to discuss the legal options available to victims of sexual abuse by a teacher, including how criminal accountability and civil claims may work in these situations and what steps survivors can take early to protect their interests.

Q: What legal options are available to victims who were sexually abused by a teacher in Pennsylvania?

A: Victims often have multiple pathways, including criminal reporting and civil claims. In many cases, prosecutors can pursue criminal charges against the perpetrator, while survivors may also pursue civil damages against responsible parties, including the individual and, potentially, the school district, depending on the facts and evidence available.

Q: How important is documentation for someone deciding whether to take legal action?

A: It’s extremely important. Even when details feel overwhelming, records such as messages, social media communications, dates, and corroborating information can strengthen a survivor’s case. Medical records, counseling records, and statements from witnesses or others who saw concerning behavior can also matter. Every case is different, but early preservation of evidence can be a turning point.

Q: Are there time limits that survivors need to know about?

A: Yes. Pennsylvania has statutes of limitations for civil claims, and those deadlines can vary based on the survivor’s age and the type of claim. The safest move is to talk with a lawyer as soon as possible so the options can be evaluated before critical deadlines are missed.

Q: What should a victim consider regarding reporting and cooperating with authorities?

A: Survivors should consider both practical and emotional impacts. If they want criminal accountability, cooperating with law enforcement or prosecutors may be part of that process. At the same time, civil litigation has its own procedures. A skilled attorney can explain what to expect, help coordinate next steps, and protect the survivor’s interests throughout.

Q: What would you say to someone who feels unsure whether they “qualify” to bring a case?

A: Sexual abuse within a teacher-student relationship is inherently harmful, and survivors don’t need to have everything figured out at the start. A consultation can clarify what happened, identify legal theories, and outline the next steps. There are options, and you deserve information about them without pressure.
