him  and  which  he  has  practiced  in  various  more  or  less  controlled  situation

.  It means that speaking ability is a form of productive skill verbally which the students
can practice the speaking English naturally based on the context. Meanwhile, Luoma states that speaking skill are an important part of the curriculum
in language teaching, and this makes them an important object of assessment as well. Assessing  speaking  is  challenging,  however,  because  we  expect  test  scores  to  be
accurate,  just  and  appropriate  for  our  purpose

.  It  means  to  know  the  students’ speaking ability, it can be measured with the appropirate assessment.
Based on the explanation above, the researcher concludes that the speaking ability is verbal  intellegence  in  producting  language  naturally  to  achieve  to  communicative
competence measuredby five criteria: grammar, vocabularry, comprehension, fluency and pronunciation.

to see how the process through which to produce a product.
Arends in Alwasilah said that assessment has six types, there are: 1.   Performance assessment
Performance assessment done to see the results perform students in speaking, in this type students usually given problem situation used to test students perform.
2.   Authentic assessment Authentic  assessment  is  similar  with  perform  assessment.  In  this  assessment  the
students  given  a  real  life  setting.  While  in  authentic  assessment  or  assessment perform, things to note that the assessment should focus on the skills of the students.
3.   Portfolio assessment Portfolio  assessment  is  done  by  assessing  the  works  of  students  in  the  form  of

Assessment  checklist  is  systematically  prepared  based  on  certain  criteria  and indicators  so  that  the  teacher  is  marking  the  time  of  assessment  and  based  on  the
results of the checklist on each indicator and then the teacher do the final assessment is based on a predetermined scale

. Assessment is a way to know outcome of the students ability to learning. In assessing
each  capability  requires  its  own  way,  the  performance  assessment,  autentik, portfolios,  learning  potential,  the  assessment  within  a  group  and  checklists.  In
learning  speaking  usually  used  performance  assessment  because  students  are  based on assessed result of their performance in the classroom, when they are convey their
expression,  storytelling,  or  when  they  convey  the  information.  Assessment  is  done not only to assess student learning outcomes but also assess students learning process
by looking at students abilities. Assess students speaking ability is not an easy thing to do. The success of a teaching can be known the results through increased learning
