<p>I don't know how common the usage is, but here are some of the rules governing the notices to students at the Ivy League:</p>

<p>Following is a report on the practice that dates from 2-3 years ago. There was some discussion about Mona Lisa's school a few days ago on a similar practice. </p>
<p>A Wink and a Nod</p>
<p>Colleges are courting their best students earlier in an effort to win their affections. Here are some of the techniques they're using.</p>
<p>Dartmouth College "Likely" letter<br>
Sent before the Ivy League's agreed-upon mailing date for acceptance letters. Dartmouth says the letters are not a violation because they only hint at admission rather than grant it. "We do these letters to try to introduce some 'humanity' into the pressured admissions process," says dean of admissions and financial aid Karl Furstenberg. </p>
<p>Grinnell College "Wink" letter<br>
Not much winking and more of a straight admission. Letter reads: "I am both pleased and excited to send you this early notification of your acceptance to
Grinnell College." </p>
<p>Clark University "Love" letter<br>
A note, often handwritten, saying "how much the admissions office enjoyed reading the application or that we appreciated the effort the student made to present a thoughtful essay," says dean of admissions Harold Wingood. </p>
<p>Williams College "Early write"<br>
A committee meets every week for several weeks in January and February to "really look for the superstars," says Richard Nesbitt, director of admissions. The result: About 200 students every year receive an admittance letter two months before the rest of the pack. </p>
<p>Colorado College "Early notification"<br>
School admits about 10% of all "regular" admissions candidates about three weeks early. </p>
<p>Smith College Early scholarship notice<br>
"The fact that Smith thinks these students are special is conveyed to them," says director of admissions Audrey Smith. The message is reinforced with $2,500 a year in scholarship money and a paid position as a campus researcher.</p>
