How do I make a checkbox stay checked?

Hey - I'm super noob. Don't know much of anything about coding and I'm trying to wrap my head around this. Here is some a passage a created with a list of what I called "Qualifiers".

<input type="checkbox"name="check" value="checked"> (print: $Qualifier's Qualifier1)
<input type="checkbox"name="check" value="checked">(print: $Qualifier's Qualifier2)
<input type="checkbox"name="check" value="checked">(print: $Qualifier's Qualifier3)
<input type="checkbox"name="check" value="checked">(print: $Qualifier's Qualifier4)
<input type="checkbox"name="check" value="checked">(print: $Qualifier's Qualifier5)
<input type="checkbox"name="check" value="checked">(print: $Qualifier's Qualifier6)

Is there any easy way to make the checkboxes stay clicked once the use clicks them? Any help is much appreciated. Thank you.
