PRINCIPLES IN HANDWRITING IDENTIFICATION
Activity 1. No two writers exactly alike
Objectives:
1. to demonstrate that no two writers have had handwriting exactly alike; and
2. to validate that no one can perfectly produce a geometrically perfect.
Activity 1a: No two writers exactly alike (Principle 1)
Procedures:
1. Write one complete sentence in the box provided below.
2. Request one of your classmates to write the sentence in another box.
3. Write the same writing style.
4. Compare and contrast the two writings.
5. Describe how you would assess the two handwritings.
A. Own Handwriting
B. Classmate Handwriting
1. Do the two handwritings have the same writing style? What kind of writing style do
the writers use?
2. Do the two handwritings look exactly alike? Describe the differences between
these two handwriting styles.
Own handwriting Classmate’s Handwriting
Activity 2b: Writing geometrical dimensions
Procedures:
1. Write one complete sentence in the box provided below.
2. Write the same sentence in another box.
3. Compare and evaluate the two handwritings.
Question Guide:
1. Are the two handwritings geometrically the same in all their dimensions?
Explain.

Activity 2: Physical writing condition and position of person including writing
instrument (Principle 2)
Objectives:
1. to illustrate how one's handwriting is affected when a person writes in a
different position;
2. to describe the handwriting produced in different writing positions;
3. to determine if the writings still have some of the handwritings'
distinguishing features.
Procedure:
1. Write one complete sentence in the boxes provided below.
2. Use three different writing instruments (pens) of various brands (e.g.,
ballpoint pen and fountain pen).
3. Write the sentence in different positions like standing, setting, at the back of
your classmate, and writing the same in hurry.
4. Write the same sentence in a porous surface.
5. Use the same writing style in all sentence.
6. Evaluate these writings in its overall physical appearance.
A. Normal condition
B. Standing Position
C. Writing at the back of the classmate
D. Writing in hurry
E. Writing in a porous or rough surface

Activity 3: Maximum writing ability (Principle 3)
Objectives:
1. illustrate the maximum writing ability;
2. explain why no writer can exceed his/her best handwriting; and
3. validate that no writer can write beyond his/her maximum writing skills.
Procedure:
1. Write a sentence using your best normal writing ability.
2. Write the sentence beyond your best writing skills.
3. Evaluate the physical appearance as to its line quality, speed, pen pressure and
emphasis.
A. Contemporaneous maximum writing ability
B. Beyond writing ability
Question Guide
1. Describe the normal or contemporaneous maximum writing skills as to their line
quality, speed, pen pressure, and emphasis.

Activity 4. Combination of handwriting characteristics essential elements of
identification
Objectives:
1. Identify handwriting elements;
2. Compare the handwriting elements found on the two sets of handwriting.
Procedure:
1. Identify the writing characteristics; indicate by putting
an arrow pointing at the writing characteristics or
elements.
Initial Stroke Diacritics
Pen pressure (heavy, average, light)
Hiatus
Pen lift Terminal Stroke
Activity 5. Individuality of Handwriting
Objectives:
1. to conduct a visual examination of the two examples of handwriting;
2. to determine the subtle consistency in the handwriting;
3. to establish the normal writing habits and degree of variation; and
4. to find if the writings shared an independent, primary controlling pattern
with the author.
Procedure:
1. Take note of the writing style found from the two-handwriting sample.
2. Compare the writing stroke between sample 1 and 2.
3. Decide whether the two-sample shared primary controlling pattern.
4. Determine the existence of consistency in slant, letter size and spacing
between letters in two samples.
5. List the individual characteristics of each sample of handwriting.
Note: Always remember that there are differences between handwriting samples
created by the same person. However, you can safely assume that the documents
do not have the same author if you discover that one document or signature
contains at least one recurrent characteristic that is absent from the other sample.
1. Were the two samples written in a similar style? (Please state the style of
writing.)
