# Lesson types

> What students can book, in which lengths, and at which prices.

**Lesson types** (the sidebar entry is called Lesson types, the page title is Lessons) lists what students can book. The order here is the order on your site; use the arrows to move a lesson type.

Lesson types belong to your teacher profile, so save your [profile](/docs/teacher/profile) first.

## Add a lesson type [#add-a-lesson-type]

<Steps>
  <Step title="Name it">
    Give it a name, for example "Conversation practice", and a description of what you cover and who it suits.
  </Step>
  <Step title="Pick a subject and level">
    Optionally choose one of the subjects on your [profile](/docs/teacher/profile) and a level on that subject's scale: CEFR (A1 to C2), or the subject's own levels when you gave it some. Students see both on your site. Removing or renaming the subject on your profile takes it off the lesson type, and changing its levels takes off a level the new scale lacks.
  </Step>
  <Step title="Choose where it takes place">
    **Online**, **In person** at the address you enter, or **Online or in person**, where each student picks when booking. Your site says a lesson is in person; only students who booked see the address. Changing this later leaves lessons already booked where they were.

    When your school has [locations](/docs/teacher/locations), an in person lesson type can pick a **Room** instead of a typed address. It then uses that location's address, and booked students see the room, the location and the address on their lesson page and in their emails.
  </Step>
  <Step title="Choose lengths and prices">
    Tick each length you offer and set its price in your site's currency. A price of 0 makes it free.
  </Step>
  <Step title="Save">
    Leave **Show on my site** on to publish it. A hidden lesson type stays in the list but students cannot see it.
  </Step>
</Steps>

## Trial lesson [#trial-lesson]

Choose **Add a trial lesson** for a first lesson to get to know a new student. A trial has one length, can be free, and each student can book one trial with you. You can have one trial lesson. It does not count against your plan's limit.

## Plan limits [#plan-limits]

The Free plan allows 2 lesson types besides the trial; Pro is unlimited. The page shows how many you use. When you reach the limit, new lesson types are refused until you upgrade or archive one.

## Hide, archive and delete [#hide-archive-and-delete]

- **Hide** takes a lesson type off your site and keeps it.
- **Delete** removes one for good, but only if no lesson was ever booked with it.
- **Archive** is for a lesson type with bookings: it leaves your site and your plan count, and past lessons keep it. **Restore** brings it back, unless that would pass your plan limit or a second trial, or its room has been archived since: then edit it to pick another room or type an address, and restore it.

## Currency [#currency]

Prices use the currency in [Site](/docs/teacher/site). Changing it does not convert prices: 25 EUR becomes 25 USD. Aula asks you to confirm.

[Packages](/docs/teacher/packages) and monthly plans are built from your lesson types.
