Dear Dr. Taltabino: 
 
Greetings! 
 
<div style="text-align: justify;">
It is with great pride and honor that I am expressing my profound interest to secure a secondary teaching position in your reputable institution.</div>
<div style="text-align: justify;">
 </div>
<div style="text-align: justify;">
I received my Bachelor of Secondary Education degree from Bulacan State University College of Education. I graduated Cum Laude and was a recipient of the scholarship program of the Department of Science and Technology. I also passed the recently conducted Licensure Examination for Teachers (LET) Secondary Level. Moreover, I was also recognized as one of the topnotchers in the national level for gaining a weighted average of 88.40%.</div>
<div style="text-align: justify;">
 </div>
<div style="text-align: justify;">
As a teacher, I am optimistic that students will discover their actual fortes and abilities as I provide a learning environment that engages their eagerness to discover things, to learn independently, to be scientific and critical thinkers, and to be confident in their own self while fostering camaraderie among their classmates.</div>
<div style="text-align: justify;">
 </div>
<div style="text-align: justify;">
I understand how vital education is, as the foundation of the young people to achieve success in any undertaking set before them. This is why my greatest goal is to nurture young minds and help them blossom into well-rounded, responsible and successful citizens.</div>
<div style="text-align: justify;">
 </div>
<div style="text-align: justify;">
I believe that my knowledge, skills, expertise, combined with my work ethics, and strong devotion to educate students would be of great service to your institution as a whole.</div>
<div style="text-align: justify;">
 </div>
<div style="text-align: justify;">
I look forward, with great anticipation, to hearing from you and discussing many ways in which I can make a significant contribution to your highly acknowledged school.</div>
<div style="text-align: justify;">
 </div>
God bless and thank you. 
 
 
Respectfully yours,
